I have been trying to demodulate a vector of data sent using a file
using qam demodulation on the grc. I am stuck as i don’t recieve
on my output file source. The output file is blank.when I change
schemes like gmsk,qam or bpsk or dqpsk, there is a very small change in
constellation. But i am not receiving my data back. I have attached my
file for reference. could you please suggest debugging tips or ideas to
my source file data after demodulation.
