Requirements

• GnuRadio v3.8.5.0 (Branch: maint-3.8)
  • Dependencies for Ubuntu
• UHD v4.1.0.5
• Eigen3
  • sudo apt-get install libeigen3-dev
• Qt5Qwt6 (should be installed with the dependencies of GnuRadio v3.8)
  • sudo apt-get install libqt5opengl5-dev
• QWT (should be installed with the dependencies of GnuRadio v3.8)
  • sudo apt-get install libqwt-qt5-dev

Installation

git clone https://github.com/ceyhunozkaptan/gr-mimo-ofdm-jrc.git
cd gr-mimo-ofdm-jrc
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

Usage

Packet Generator App:

This application can generate Data Packets (DATA) or Null Data Packets (NDP). It utilizes an internal UDP socket to send packets to the GnuRadio flowgraph.

gr-mimo-ofdm-jrc's Issues

There has errors in examples grc

When I used gnuradio- companion to open examples/simulation/radar/mimo_ofdm_jrc_radar_sim.grc. It will reports these errors:

I had compiled and installed this project without any errors. What wrong?

Hello, I have a new problem.I used two antennas as the transmitter and one antenna as the receiver to verify only the communication function. Set related parameters as follows：

          Hello, I have a new problem.I used two antennas as the transmitter and one antenna as the receiver to verify only the communication function. Set related parameters as follows：

Sample rates: 1MHz
Gain: 50 dB
Center frequency: 5 GHz

When I send an NDP frame, I can detect frames, but the constellations are messy. The following error message is displayed: DATA Checksum is wrong--Dropping Packet, bytes: 7.

When I sent the precoded DATA frame, the number of bits dropped was even higher:

Do you have any idea what the problem might be?

How do I mark the type of transmitted data stream？

Hello, I'd like to ask you a question. I am sending a stream of DATA from Socket PDU module, but I don't know how the Stream Encoder module will mark it as NDP or DATA. And I run the sender flowchart and it shows the following error:

Do you know how I can solve this problem？

Block Missing

Hello, I am having a problem with the example you provided. As you can see in the picture above, when I open the "mimo_usrp_alignment_4tx_2rx.grc" in "example", it shows that some blocks are missing. I have installed GNU Radio version 3.8.5.0 in Ubuntu 20.04 as per the tutorial. Can you provide some information please, appreciated.
