Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is well-known to be effective against multipath distortion. Channel estimation for mobile OFDM systems requires transmission of pilot symbols. This paper addresses the important issue of selecting the location of these pilot symbols, so as to achieve low error rates. It addresses the effect of Doppler spread of channel on different pilot arrangements and propose a new scheme for inserting pilot symbols. It is shown here, that for pedestrian channels proposed scheme performs better than other pilot insertion schemes.
