Gesley, There's a reason that the code you are trying to make work is no longer in the distribution. It didn't work well. It has been replaced by the gmsk2 code and examples. > I couldnt find any reason for why this is happening. I thought that > maybe its because of some kind of a time delay.

Have you plotted the raw data you are receiving from the USRP, perhaps in octave? What are the maximum and minimum values of both the real and imaginary components? If you're not getting anything in the file, perhaps the correlator is never seeing the synchronization pattern. Have you instrumented the correlator?
