Hi Frns !
Can any body plz enlighten me regarding the following issue -->
In an OFDM system employing adaptive Modulation (ie diff Q-ary schemes as per diff SNRs) using data multiplexed pilot bits for channel information at receiver, How do the min number of required pilot bits change depending on the Q-ary scheme used ??
ie If one goes for higher order modulation (say from 4-ary to 16-ary) how does the required pilot bits for succcessful estimation change ???
