ABSTRACT:
A method of channel estimation is provided. The method is applied to a communication system having signals transmitted via a plurality of pilot and non-pilot sub-channels. The method comprises the steps of obtaining a first and second channel responses of each pilot sub-channel using pilot symbols received during a first and second time duration respectively, obtaining an estimated channel response of each pilot sub-channel by averaging the first and second channel responses thereof, and obtaining an estimated channel response of each non-pilot sub-channel by interpolation of those of the pilot sub-channels.
