TIMEOUT on OFDM

Hi All,

I am testing OFDM transmission. When I transmit from a file using
benchmark_ofdm_tx.py, I can receive 75% pkt at the receiver side using
banchmark_ofdm_rx.py, and all of them are right. When I stream the input
data to a port via UDP, and let benchmark_ofdm_tx.py get data from this
port
and transmit, at the receiver side, I can receive 60% pkt and only 15%
are
right; meanwhile there are lots of ‘TIMEOUT’ at the receiver side.

Can anyone help me on, 1) when transmit from a file, why I can not
receive
100% pkt, now I transmit 76 pkts but receive 59 pkts from pktno0 to
pktno58,
and lost the rest? 2)If I get the data input from a port rather than
from a
file, why I received lots of false pkts and got TIMEOUT at the same
time?

Here is the command I used:
sudo ./benchmark_ofdm_tx.py -f 490M -T A --tx-amplitude 5000 -v -i 64
–fft-length 64 --occupied-tones 52 --cp-length 8 -M 0.2 -s 2000
–from-file
file

sudo ./benchmark_ofdm_rx.py -f 490M -R A -v -d 32 --fft-length 64
–occupied-tones 52 --cp-length 8

Thanks in advance,
Brook
