Profound increase in no. of correct packets on demodulating

Hi everyone

I am currently on a chore which requires taking data from USRP and use
it further down the lane.
I write the data from the USRP onto a file and keep noting the no. of
correct packets received.
But today the most puzzling thing happened!!

After storing the USRP data on the file when I d emodulated the file
separately…the no.of correct packets were more than those axctually
treceived in real time!!

I cant think of an explanation for this n I hv repeated the simulation
many-a-times to observe the same thing!!

As an illustration, suppose I received 1000 packets online of which 500
were correct and I stored the USRP data in a file,…then on
demodulating the file I get 1000 packets of which 587 are
correct!!!

How to explain this sudden increase in quality of packets???
Kindly help…
Thnx in advance

Hi,.
Currently I am also working to calculate the BER by varying the
transmitted power.
From the posts here, it seems that u did some work related to BER plots.
Can you help me . Bcs I am also facing the packet loss. The last packets
are being lost and I dont know how to transmit Bits …help
required…

thanks in advance,
