suscan's Introduction

Suscan - A realtime DSP library

Important note: if you are looking for the graphical application based on this library, it has been deprecated and removed from the source tree. Suscan (GUI) was a GTK3-based application with poor performance and responsiveness that was eventually replaced by the Qt5 application SigDigger. You will still need Suscan (library) in order to compile SigDigger.

Suscan is a realtime DSP processing library. It provides a set of useful abstractions to perform dynamic digital signal analysis and demodulation. Suscan offers features like:

Multicore-friendly signal processing, based on worker threads
Generic ASK, FSK, PSK and audio demodulators
An extensible codec interface
Configuration file API (XML)
Source API based on SoapySDR

Getting the code

Just clone it from the GitHub repository. Make sure you pass --recurse-submodules to git clone so all required submodules are also cloned.

% git clone --recurse-submodules https://github.com/BatchDrake/suscan.git

Building and installing Suscan

In order to build Suscan, you will need the development files for the following packages:

sigutils
fftw3
sndfile
SoapySDR
libxml-2.0

If you are in a Debian-like operating system, you will also need cmake and build-essential.

After installing all dependencies, enter Suscan's source directory and compile by typing:

% cd suscan
% mkdir build
% cd build
% cmake ..
% make

If the previous commands were successful, you are ready to install Suscan in your system by executing (as root):

# make install

You can verify your installation by running:

% suscan.status

If everything went fine, you should see the message:

suscan.status: suscan library loaded successfully.

suscan's Issues

Add Viterbi decoder

Add a GUI to configure a Viterbi decoder. Some insights by EA4GPZ:

Most people use CCSDS polynomials
These polynomials can be applied in different order, and one of them may be inverted. See http://destevez.net/2017/01/coding-for-hit-satellites-and-other-ccsds-satellites/
Bits must be grouped appropriately to fit the beginning of each codeword. If the size of the codeword is n, there will be n possible groupings. This means that the Trellis tree must be traversed n times in parallel with increasing symbol offsets.

Summary: 95% of the time we will have CCSDS polynomials with rate = 1/2 and k = 7. This default configuration must appear somewhere in the GUI (like a preset)

cc: warning: argument unused during compilation: '-s' [-Wunused-command-line-argument]

When making a release build, clang outputs the following for each .c file:

cc: warning: argument unused during compilation: '-s' [-Wunused-command-line-argument]

I'm assuming this is supposed to be the strip option on gcc, which is AFAIK a linker option. Therefore, it should not be set on CMAKE_C_FLAGS_RELEASE but rather on whatever the linking equivalent is.

Modulo de analisis "offline"

Hola Gonzalo.
Hay varias razones para que el analisis se haga offline a partir de grabaciones:
1.- Cuando las señales son desconocidads y/o no documentadas, son necesarias varias grabaciones para llegar a resultados aceptables.
2- Las señales "burst" de muy corto ciclo de trabajo suelen pasar desapercibidas en los sitemas en tiempo real.
3- Las señales ARQ adaptativas pueden ir cambiando de modo sobre la marcha, lo que dificulta su analisis en tiempo real.
4- Hay vario modem hibridos que cambian la modulacion sobre la marcha, lo que puede inducir a errores.

Hay mas razones para que el analisis se haga offline como en SA, lo que no es obice para que tambien se puedan hacer muchas cosas en tiempo real, especialmente cuando ya se conocen los parametros de la señal bajo analisis.

Si consideras la posibilidad de implemetar este modo, podemos aportar ideas al respecto.

Saludos.
ANgazu.

Refactor inspector API

The suscan_inspector class actually refers to a PSK inspector and this is okay for now. However, as we plan to add OFDM analysis support in the future, the inspector class must be an abstract class from which we derive different concrete inspectors (PSK, OFDM, etc).

Also, inspector configuration is set by passing an ad-hoc structure describing several PSK parameters. This is not scalable: communication between the inspector and the client (i.e. the GUI) must be generic and discoverable, so that the GUI can create a new interface for new inspectors at runtime.

We can do that by improving the suscan_config_t type and adding namespaced keys like agc.enabled, agc.alpha, costas.order, costas.alpha, etc. There will be an API to test the existence of a given namespace, which will be used by the GUI to create the appropriate controls in the inspector tab.

Define a proper versioning system for Suscan

Suscan lacks a sane versioning system. This versioning system should provide the following information to the user:

Current API version (header files) + macros
Library API version and maintenance version
Build string

Add additional spectrum sources

Add and/or implement the following spectrum sources:

Cyclostationary analysis for all sources.
Simple time derivative
Absolute value of the time derivative
Quadrature-based FM detection (only for FSK sources)
Phase spectrum

Suboptimal implementation of decimator

Reimplement source decimator as a CIC filter as described in https://en.wikipedia.org/wiki/Cascaded_integrator%E2%80%93comb_filter#The_CIC_filter

Support build on Windows systems

Leveraging the new cmake build system, make suscan available to Windows systems. Due to the impractical complex number support in Visual Studio, use MinGW (32 and 64 bits) instead.

Can't test suscan library

I build dependencies (suscan) and install it. When i run "suscan", to test installation, i received next message: "suscan: error while loading shared libraries: libsigutils.so.0: cannot open shared object file: No such file or directory". Previously i build sigutils and install it too.
Ubuntu 18.04, x64.

Define SOVERSION

Suscan is missing SOVERSION, required for tracking ABI changes.

Improper handling of unsupported rates

Some SDRs supporting fixed sample rates (like AirSpy) will not report invalid sample rate configuration. Instead, they will deliver samples at the closest supported rate. This has an impact on interface responsivity as Suscan will fail to deliver inspector and PSD data on time.

Cannot perform full bandwidth filtering

If the inspector channel's relative bandwidth is beyond 50% the sample rate, the inspector will refuse to open. Full bandwidth demodulation should be allowed.

Implement GPU offloading

SigDigger still takes a lot of CPU time to channelize and demodulate. Offload part of the process to the GPU if available.

Implement symbol transition analysis

In certain modulations (especially OPSK and pi/4-QPSK) not all symbol transitions are allowed. In order to identify them, we must estimate the probability of every possible symbol transitions. This transition analysis must be performed for both consecutive and alternating symbols

Replace build system by CMake

Current autotools-based build system is cumbersome and rather slow. Switch to CMake to ease porting to other operating systems.

Is a waterfall expected ?

Hi,
I try to run SUScan with a rtl-sdr stick as default source (@300000 sps).
When I click on the start button a spectrum line is run, a lot of CPU is used by Xorg but nothing moves anymore on the screen except, sometimes, some red lines/rectangles (see attached screenshot).
No waterfall and the window seems stuck :-(
The netbook used is not very powerful (AMD C-70) but it runs gqrx with a spectrum display, a waterfall and its demodulators just fine :-/

Any hints ?

Extend wide spectrum analyzer parameters

The wide spectrum analyzer should allow:

Configuration of walk strategy (progressive or stochastic)
Configuration the spectrum partitioning (continuous or discrete)
When the range is below the sample rate, no hop should happen at all and the frequency should remain fixed.

Configure suscan's global directory

Many configuration defaults are loaded from hardcoded search paths involving the system. Design API to specify additional search paths from environment variables.

Adjust spectrum message interval according to effective samp rate

There are two cases in which the spectrum message interval does not behave as it ought to:

a) The throttle control has been adjusted to a sample rate that is different from the source sample rate
b) The speed at which Suscan processes samples is slower than the source rate.

In both cases, Suscan should keep a measure of the current rate and update the spectrum intervals accordingly.

Wrong linker library in file

Hey
This is a weird issue:
While compiling, I got this:
ld: library not found for -l-L/usr/local/opt/qt/lib
It turned out to be inside build/CMakeFiles/suscan.dir/link.txt
There was an empty -l . I removed it and compile succeeded

Fix codec output behavior

There are several aspects of codec GUI behavior that should be fixed:

Berlekamp-Massey should be implemented for non-binary constellations
The offset spin button is disabled and offset cannot be controlled manually
Codec symbol views should inherit settings from the source symbol view

DC offset removal should be enabled by default

I have uploaded an aur pakage for this proyect

also made one for sigutils :)

Improve performance of the channel worker

The current channel worker performs innecesary copies of the data buffer, and redundant FFTs. To prevent this:

Add multiple overlapping FFTs, and copy only the last half.
Zero-copy data read
Decouple read thread from processing thread

Implement symbol translator

In most non-differential modulations (and many differential ones too) there is a symbol labeling ambiguity that cannot be tweaked from GUI. A new codec (e.g. "Symbol translator") can overcome this limitation by providing some dialog to set symbol labels manually.

Also, since this codec would have its own GUI, it should not be accessible from the Encoders / Decoders menu (maybe add an "internal" field to the suscan_codec_class?)

SigDigger appimage audio clipping at 32,000 up

Wavin drake, i was testing this on my skywave linux install, and the audio gets choppy at 32,000 and up. is there any thing i can do to fix this by tweakin settings in the program?

Document existing features

The project is not documented at all, and we cannot rely on the intuitiveness of the UI any longer. Some documentation effort must be performed here.

suscan crashing with "invalid opcode" error

Few days ago everything worked fine on Ubuntu Studio 20.04 on the same PC. Any ideas what went wrong?

SoapySDR headers not found on macOS

Hey
As you know I test on 2 MacBooks.
On one MacBook, I have compiled SoapySDR from source, so there's no issues.
On the other one, I have installed it via brew. On this second machine, I get error:
/Users/mehdi/Documents/source/suscan/analyzer/source.h:30:10: fatal error: 'SoapySDR/Device.h' file not found
Well I fixed it temporarily by setting the CPATH variable in command line.
Couldn't find any strange things in your CMakeLists

Suscli radio profile setting not changing regardless of index or name used.

Before I forget. With the latest Suscli dev branch, I'm unable to change the radio profile using the following commands

Suscli radio profile 2 (replace 2 with any profile index or name)

Initially I was stuck with whatever UI Profile was (index number 1). I then deleted the Suscan sources file. Used Suscli makeprof to create new profiles which resulted in the Default, Airspy, and an IP/port profile.

Now when I start Suscli radio, no matter which profile I pick, it's the index number one Default device (is the Airspy just like the number 2 index) so at least I can use it. However, I think something is preventing the user from changing profiles.

Define different analyzer classes

An analyzer is a generic object that deals with a signal source and does some processing on top of it. Right now, the only purpose of the Analyzer is to channelize and feed inspectors, but we may want to do different stuff in the future, like:

Perform a wide spectrum sweep (ordered or random), returning PSD messages
Locate activity in specific channels and print alerts
Integrate the whole spectrum for a long time
Perform channel fingerprinting
Perform scientific calculations? (this could be useful for radioastronomy and stuff, and would allow a nice reimplementation of QStones)

All these features share the need to deal with a signal source in an asynchronous way, while they slightly differ on what to do with the signal. Some of them channelize the signal, some others settle for integrating the FFT one way or another. The inspector abstraction (which is basically an interactive demodulator) falls short in scenarios like these.

Add nonlinear baudrate detector for FSK signals

Using the same ideas behind the nonlinear baudrate detector for PSK, implement a baudrate detector for FSK differentiating the phase and taking the absolute value.

suscli exceptions on Mac OSX

Any idea why these exceptions print when running suscli devices

Descramble symbols directly from GUI

The current Berlekamp-Massey implementation can deduce the scrambling polynomial on BPSK signals. The next obvious step is to use this information to descramble a frame. This new feature should allow us to:

Use the scrambling polynomial to feed a multiplicative descrambler
Use the scrambling polynomial to feed an additive descrambler, by providing information about the synchronization sequence (i.e. where the sequence used to deduce the polynomial is w.r.t the sequence we want to descramble as a frame offset)
(Optional) Perform auto-synchronization of the additive descrambler.

Channel detector does not work properly for real signals

For some reason, in real signals, the channel detector representation is only working for the positive part of the spectrum. Also, the algorithm is still failing to difference the noise floor from the filter stopband.

Multiple warnings in spectrum widget realization

This has been observed for a while now, in the standard error output:

(suscan:23349): Gdk-CRITICAL **: 23:05:35.096: gdk_window_create_similar_surface: assertion 'GDK_IS_WINDOW (window)' failed

(suscan:23349): Gtk-CRITICAL **: 23:05:42.405: gtk_widget_grab_default: assertion 'gtk_widget_get_can_default (widget)' failed

This could imply that we are failing to create the best surface for the spectrum widget. Although it is not prioritary, it is polluting the error output, potentially masking other problems.

Undefined reference to `su_channel_detector_sample_was_consumed'

Tried to build from master, got two linker errors

analyzer/inspector.c:373: undefined reference to `su_channel_detector_sample_was_consumed'
analyzer/inspector.c:380: undefined reference to `su_channel_detector_get_last_sample'

Channel distortion on audio inspector running with narrow channel filter

For some reason, if the audio inspector's channel filter is reduced, the resulting signals tends to have many negative peaks that are correlated with poor audio quality. On the other hand, increasing channel's bandwidth seems to fix this problem. Although there is a workaround for this (high bandwidth and then adjust audio cutoff) this is not the expected behavior, as linearity is being lost somewhere.

suscan doesn't actually use volk?

Hi, when packing this for arch I noticed the following warning. Looks like suscan isn't actually using volk, if that's the case, the dependency can be removed. Could you investigate? Thanks 😁.
