[Discuss-gnuradio] running OFDM on USRP2

[bin zan]

Hello, 
       I was trying to run following OFDM command on USRP2, however, I got a bunch of "SSSSStime out" at the receiver side.  

./benchmark_ofdm_tx.py -f 2.4G -i 512 --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

I wonder if there is any one successfully running OFDM on USRP2, what are the command parameters you are using and if there is any modification in the code, can you let me know. 

Thanks,
Bin
