Very simple static equalizer for OFDM. 
This is an extremely simple equalizer. It will only work for high-SNR, very, very slowly changing channels.
It simply divides the signal with the currently known channel state. Whenever a pilot symbol comes around, it updates the channel state on that particular carrier by dividing the received symbol with the known pilot symbol.
