I am trying to learn something about the OFDM system and I found that in the code of OFDM channel estimation block, it uses the synch. word and without pilot symbols. I think it should also have some function related to the pilot but there is not. Could someone help me about this? This means that if you want to implement channel estimation using pilot with GNU radio you need to use a custom module, is this correct? Any help would be greatly appreciated, thanks!
Best regards
Philip
