Résumé:
An accurate approach to compute the bit error rate expression for multiuser chaosbased
DS-CDMA system is presented in this paper. For more realistic communication
system a slow fading multipath channel is considered. A simple RAKE
receiver structure is considered. Based on the bit energy distribution, this approach
compared to others computation methods existing in literature gives accurate
results with low computation charge. Perfect estimation of the channel coefficients
with the associated delays and chaos synchronization is assumed. The bit error rate
is derived in terms of the bit energy distribution, the number of paths, the noise
variance, and the number of users. Results are illustrated by theoretical calculations
and numerical simulations which point out the accuracy of our approach.
