Re: [Discuss-gnuradio] OFDM implementation

I've checked out the latest version (5772) and tried running the
benchmark_ofdm files.  The benchmark_ofdm.py and ofdm_benchmark_tx.py seem
to be working.  But when I use the benchmark_ofdm_rx.py I get the following

python: gr_ofdm_correlator.cc:105: gr_complex
gr_ofdm_correlator::coarse_freq_comp(int, int): Assertion `symbol_count <=
1000' failed.
Aborted (core dumped)

Currently I'm using two USRPs on one PC and tried transmitting across the
air. (I modified the benchmark_rx with 'which=1').  I ran the scripts as
./benchmark_ofdm_rx.py -f2.45e9 -d100
./benchmark_ofdm_tx.py -f2.45e9 -i200 --tx-ampl=200

I hope you can give me some pointers to solve this.
