How can I add channel encoder/decoder and equalizer in usrp_transmit_path.py and usrp_receive_path.p

Hi:

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:

Tx link:
Data bit stream -> Hamming Coding -> QAM modulation -> add training
sequence
-> (send to the air)

Rx link:
QAM demodulation -> Decision feedback equalizer -> Hamming Decoding ->
Bit
stream

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
usrp_transmit_path.py?

If it is too easy for a beginner to modify the example code, what could
be a
better way to build up such a communication link?

Thanks,
Rachel
