Dear All
I try to transmit Audio File using QPSK modulation and Raised cosine
waveform on GNU radio platform
I can transmit a clear audio file, constellation sink, and amplitude
graph. but when I try to receive using another Laptop the USRP cannot
receive the transmit signal so I cannot hear the audio file
see the file here and please help me if I made a mistake
1.even The USRP transmitter give red light and also the USRP receiver
side gives the green light but I don't know why
