Abstract
The use of high level trellis-coded modulation with fading counter measure techniques such as equalisation, space diversity, slow frequency hopping and interleaving is proposed for wideband mobile communications. The symbol error rate (SER) performance of those systems on presence of additive white Gaussian noise (AWGN), co-channel interference (CCI), Intersymbol interference (ISI) and frequency selective multipath Rayleigh fading are investigated. Several combining schemes for equalisers and diversity are evaluated by computer simulation. It shows that by choosing a proper interleaving size, number of the frequency hopping and the combining scheme of equaliser and space diversity, the proposed system gives considerable performance improvement and can cope with the frequency selective multipath fading in wideband mobile communication systems.
