I am looking gr-ieee802-11 module.
a part of the source code is pasted here (
I have a question on the following statement:
if(rel >= 0 && (rel < 128 || ((rel - 128) % 80) > 15)) in
if(((d_count + o) % 64) == 0) in
I am wonder what do these numbers(128, 80, 15, 64) and modulo operation
have logical meaning in IEEE 802.11p PHY frame?
I’ve read 802.11 OFDM specification, thus I have knowledge about it,
but I have no idea what are roles of these things in implementation.
