Hi Sajjad, >From a quick first glance without testing the flowgraphs on any hardware i've noticed the following issues:
Corrections for both: 1) Your Tau and Max Deviation values are not the same. 2) you are sending data over TCP at 250e3 samp_rate to the server which is expecting 50e3 3) lower the refresh rate on the Wx FFT to cut down on CPU usage Tranceiver_Client Corrections: 1) 50e3 * 2.83447 is not 250e3. make the resample rate = 5 in your polyphase arbritrary resampler. 2) Your low pass filter is decimating by 2 and should be 1 Tranceiver Server correcitons: 1) in your polyphase arbritrary resampler, you should make the number of phases = 32 and then multiply the samp rate in the taps by 32 also.
