Hi,

I’m using benchmark_ofdm tx and rx in 2.4 GHz. I’m trying to transmit a

fixed size of payload everytime (1328 Bytes). My problem is I don’t know

what values I must put in the parameters: fft-length, occupied-tones,

cp-length. I know that fft-length is the total number of subcarriers, cp

the

cyclic prefix, occupied-tones number of subcarriers used for data. I

have

been running modifications of these benchmarks, and the best performance

I

get is when the values of these parameters are: fft-length 512, cp 128,

occupied tones 300. In this case, the 80 % of paquetes I receive are

right.

How can I calculate the apropiate values ? Must I used the parameter

“-s”

for fixed the packet size to the one I want, 1328? what happen with the

“-i”

and “-d” in the transmitter and the receiver?

## Thank you
