Convolution code performance

[Akshay Singh]

We are trying to put a convolution encoder in the qpsk transmitter example and a decoder in the qpsk receiver example but we are not able to do it correctly. Has anyone tried tinkering with the QPSK example of USRP in simulink?

What is the issue you are facing> I did it long ago, it was pretty simple. Sometimes the error rates are high with convolution encoding due to error propagation.
