Hi Tom,
but as far as I see from the code, only max. 16 subcarriers are handled
for a IFFT.
That is to say:
Tx-chain:
16 byte data → CRC → make packet → mapper_bcv → insert preamble →
IFFT → cyclic prefix
And when the size of the data exceeds 16, say 17, then anonther Tx-chain
goes through for the 1 byte.
So I thought, with the option -s 16 I’m sending the ‘basic’ size of the
each Tx elements.
And when the receiver side does not detect all right, the reason may be
that the transceiving happens too fast?

(Then it transmits 2500 packets each of size 16)
I get about 2300 to 2370 packets received at the receiver side.
16 subcarriers is a really small number to use and it’s likely not being
picked
up by the receiver.
