Hi All, I am working on OFDM. I use benchmark_ofdm_tx.py and benchmark_ofdm_rx.py to transmit and receive data right now. ./benchmark_ofdm_tx.py -f 440M -T A --tx-amplitude 5000 -v -i 128 --fft-length 128 --occupied-tones 80 --cp-length 32 ./benchmark_ofdm_rx.py -f 440M -R A -v -d 64 --fft-length 128 --occupied-tones 80 --cp-length 32 However, at the receiver side, I can not receive pkt=0 and pkt=1 every time. Most of the time, it receives from pkt=2. Can anyone tell me why is that and how to fix it, please? The second question is, at the TX side, TX actually transmits 503 pkt; but at the RX side, RX only receives part of these. The RX stops receiving when received pktno is 380. The third question is, why the value of decimation should be half of the value of interpolation? Thanks for any reply.
