Abstract :
LS and MMSE phase noise estimation and correction schemes are proposed for orthogonal frequency division multiplexing (OFDM). Their performance is characterized in channels impaired by AWGN and multipath effects. The required separation between pilot symbols in the OFDM frame is analyzed leading to the conclusion that the proposed schemes are feasible with a very small efficiency loss caused by pilot insertion.
