Abstract:
|
In this paper we propase a TOMA Slow Frequency Hopping-Trellis Coded BPSK scheme for wideband cellular mobile communications. TCM wilh channel interleaving allows us to achieve coding gain without bandwith increase on Rayleigh fading channels with AWGN, and FH provides the intrinsic frequency divetsity to combat the Rayleigh fading. The dynamic multipath radio channel has been simulated by means of a simple two-ray model wilh a delay spread higher than the in verse of the transmission rate. Instead of a conventional Viterbi algorithm, a Near Maximum Likelihood detector with a good performance/complexiry tradeoff has been used to avoid the effects of linear intersymbol interference (ISI). |
