C++ DSP library

plasma-dsp

C++ DSP library

Goal

To be the de facto DSP library used in new projects, and the fastest, for the RF portion (acquisition, tracking, recovery) of DSP with SDRs.

What it's NOT

• Currently, it's not in a functional state, not unless you know exactly how to get to the usable code
• A replacement to anything, it's just a different library
• For embedded hardware, although this could change in the future
• For data processing after you recover the bit stream, there are a plethora of libraries for that
• A fixed-point integer DSP library, modern processors work just as well with floating point when optimized properly

What it IS

• A work in progress, I'm still trying to figure out the best format for this library so please don't use it just yet
• A collection of optimized blocks to perform RF DSP operations on both receivers and transmitters
• A floating-point DSP library, modern processors can process those just as fast as fixed-point when optimized properly
• For RF processing, to get you from the RF to the bit stream (receivers), or from the bit stream to the RF (transmitters)

What it could be

• A teaching tool: I will try to document every block and its inner workings, and provide a "typical" implementation alongside the "optimized" implementation
• You could use this for audio processing, but most of the blocks will not have a purpose and there are much better specialized libraries available
