Does this need to be in real time?

If the answer is yes, you will most likely want to create a block that
operates on the complex samples, and you can insert it prior to the
demodulation block in the benchmark_rx program.  I'm not sure how up
to date the how-to is, but it is at least a place to start:

If the answer is no, the easy method would be turn on logging in the
benchmark_rx and then import the data into matlab/octave for
processing.  Then you can do any mathematical operations you want
pretty easily. (you may want to do this as a 'first step' even if it
needs to be real time to help develop your code)
