I am using Gnu Radio Companion, and USRP2 RFX1800 daughter card. I
created on Tx end: a File source and USRP2 sink, and on Rx End: created
USRP2 Source and A File sink. The two USRP2’s are connected with RF
cable with attenuator, to see under less noise conditions the trials and
are separated by around 2-3 meters.
Am sending a +1 to -1 amplitude square wave samples from Tx and when i
capture on Rx end its not almost a square wave. I have generated the
above .py scripts using grc. Kindly help me out in correcting the above
scripts, if am not correctly done, As a newbie to gnuradio.
At least i got some wave form on the rx end. But when i try to execute
the tx_samples, rx_streaming_samples, i did’t even got this result for
the same Interp and decimation factor, what am making mistake in the
experiment?. And am using the encode.cc and decode.cc to encode IQ
samples text file and decode the samples into I Q form, to
analyse in the gnuplot(MATLAB,etc). Can also see the files here.
