Abstract :
We study the performance of the wideband orthogonal frequency division multiplexing (OFDM) system in conjunction with channel coding based on turbo codes over a range of wideband Rayleigh fading channels. Due to their diversity effect wideband propagation channels provide similar gains for OFDM modems to those of equalised narrowband channels, resulting in substantial coding gains, when combined with turbo coding
