Re: [Discuss-gnuradio] running OFDM on USRP2

[Veljko Pejovic]

Hi,

I have gnuradio 3.2.2 installed on Ubintu 9.10 and I'm using USRP2s
with XCVR2450 daughterboards.
I tried your example but I changed the interpolation to correspond to
the decimation at the receiver:

./benchmark_ofdm_tx.py -f 2.4G -i 256 --fft-length=64
--occupied-tones=32 --cp-length=4
./benchmark_ofdm_rx.py -f 2.4G -d 256 --fft-length=64
--occupied-tones=32 --cp-length=4

And it works fine.
When I tested the example I played with tx and rx gains and the
tx-amplitude to find the best setting.

Cheers,

Veljko
