The latency between TX and RX

Hi All,

When I use benchmark_ofdm_tx.py and benchmark_ofdm_rx.py to transmit and
receive, I found that the transmitter side is faster than the receiver
side.
For example, I give a small pkt size, say s=1200, and a large file size,
say
M=5. When benchmark_ofdm_tx.py finished transmitting, at the receiver
side,
only half of the transmitted packets are received, and the receiver will
keep receiving the rest. However, if I gave a smaller M, say M=1, the
receiver will receive all the packets when the transmitter just finish
the
transmission. Why is that? How to solve it if I want to transmit a large
file? Could anyone advise me?

Thanks in advance,
Brook
