I am working on cooperative communiaction using USRP kits i have a problem in USRP communication

hi all,
i have a problem in USRP communication when i use packet encoder and
decoder in my flow graphs and do real time communication on USRP kits
then the decoder does not work correctly means the received data after
decoding will be compared with the original source data for computing
error rate but it does not show the error rate when i remove the decoder
then it will work properly and will show the results the flow graphs are
attached with this mail.

Regard Irfan U.

Is it possible that the packet decoder sees no packets because there is
no signal? The demod will simply output stuff even with noise present.
You may want to double check your setup and experiment with some test
tones to ensure good configuration, antenna setup, tuning, etc…
