[Discuss-gnuradio] OFDM serial to parallel mappping

[CHIN-YA HUANG]

Hi,

Does anyone have clear idea about how gunradio implements serial to parallel 
mapping since 802.11 has 52 channels?
I check the gr_ofdm_mapper_bcv.cc , but still have no idea about it.  
In further, I want to apply an array mapping to implement that different 
channels use different constellation. Does anyone have another comments if I 
apply an array in the gr_ofdm_mapper_bcv.cc file? 

Thanks.

Yaya
