Abstract

The authors analyse the performance of uncoded and coded asynchronous DS-CDMA systems over multipath fading channels. The fading-channel model adopted is a general one; by varying the parameters it is possible to model Rician or Rayleigh fading. Using these fading models, the authors developed the probability of bit error for the asynchronous DS-CDMA by modelling the multiple access interference (MAI) as a Gaussian process, as well as an improved Gaussian process. For coded systems, they investigated the effect of bit-to-bit dependence, due to the MAI, and fading within a codeword on the computation of the probability of bit error
