I need your help. May be any of you had such a problem before:
I use 'IEEE 802.11 a/g/p OFDM Transceiver' project, Ubuntu 13.04, GNURADIO 3.7 and (USRP N200 + XCVR 2450 + VERT2450 antenna).
I start the transmission using the first laptop and USRP N200 device by running the ./ofdm_tx.py.
Meanwhile I use the second laptop and USRP N200 device as the receiver by running the ./ofdm_rx.py. The error rate is very high.
The problem is that when I change gain in the USRP sink nothing changes (i tested it using 'wxgui_fftsink').
(I think it is a software problem since I tested it with another project. There it changes when I change gain.)
Do you know what can cause this?
Why transmission side (USRP sink) does not change according to the gain at all?
Thanks in advance!
