I am new to gnuradio and have a question regarding how to build a
communication link from scratch.
This is the communication link I want to build:
Data bit stream -> Hamming Coding -> QAM modulation -> add training
-> (send to the air)
QAM demodulation -> Decision feedback equalizer -> Hamming Decoding ->
It seems that the existing gnuradio example usrp_transmit_path.py and
usrp_receive_path.py don’t have channel coding and equalization.
Does anyone know how to (1) add channel encoder and training sequence in
usrp_transmit_path.py, and (2) add the equalizer and channel decoder in
If it is too easy for a beginner to modify the example code, what could
better way to build up such a communication link?
