Hi,
I found the OFDM IFFT caculation is very different from what I got in
MATLAB.
In detail, my command is shown below
./benchmark_ofdm_tx.py -f 10M -i 512 --fft-length=64 --occupied-tones=32
--cp-length=4 (bpsk)
The packet size is 8 bits, after a serials of operation, it added 4 bytes

Hi All,
I am working on OFDM based on benchmark_ofdm_tx.py and benchmark_ofdm_tx.py.
Can anyone give me some hint on how to adjust transmission power on each
subcarrier, please? If I set --tx-amplitude, it will be applied on all the
subcarriers, however, I want different subcarrier with differen

You can do whatever you want in the fpga. The critical part for you is to
identify the phy and mac layer components that are latency sensitive and
implement those on the fpga. You don't necessarily have to slap the entire mac
and phy onto the fpga.

Hi,
The inband registers are listed together in register_io.v, while
the non inband registers are created in different modules where the
values are needed.
Is it made like this because of timing constraints or is there something
else?
