Hi,
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
gmsk_file_transceiver.grc.
This work fine and we can see the stream video output without any
difficulty. -
To continue further I splitted the above mentioned file into
transmitter
and receiver side along with the inclusion of USRP source and sink
blocks,
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
transmission
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
USRP
platform.
Thanks in advance.

Syed Aqeel R.
