Again, I did some more work and the details are as under.
I have created a single flowgraph without USRP hardware. For your
reference the file is enclosed with the name of
This work fine and we can see the stream video output without any
To continue further I splitted the above mentioned file into
and receiver side along with the inclusion of USRP source and sink
respectively. Their flowgraphs are enclosed with the name of gmsk_tx.grc
and gmsk_rx.grc, respectively. The FFT plot shows that (vdo
transmission.png enclosed) transmitter and receiver handshakes with each
other but the signal difference between the transmitter and the receiver
side is 80 dB. I further noticed that whenever I stopped the
the received signal at the receiver further drops to -120 dB.
I really get stuck in this issue for the last two days. I need your
assistant to resolve this problem as I am a newbie in gnuradio using
Thanks in advance.
