Dear all, I'm using ath9k_ar9003 type and ath9k_htc type.
And I'm studying how packet be transmitted through wifi driver. I have researched from application layer to phy and I'm done to the MAC layer. However, I can't find any parts about data mapping to carriers. As I know, for OFDM, there're several subcarrier in specific bandwidth and user data(payload) fills subcarrier. Which part responsible for mapping? It is implemented at firmware level ? Please help me ! Thanks.
