Abstract
The coded OFDM (Orthogonal Frequency Division Multiplexing) system minimizes the effect of multipath mobile channels by using the time-frequency interleaving. But for mobile reception there is possibility that the error correction is not effective enough. In this paper we describe from the experimental results that for mobile reception the selective diversity technique improves BER performances even at high speed moving (doppler shift is 3% of the carrier spacing) and that at low speed moving the diversity technique is effective to change the encoding rate from 1/2 to 3/4.
