Effects of Multipath Propogation Delay on the Uplink Performance of Synchronous DS-CDMA Systems Communicating in Dispersive Rayleigh Fading Channels

摘要

The effect of the maximum asynchronous arrival time difference (AATD) of the delayed multipath components on the uplink performance of synchronous DS-CDMA systems is investigated, when communicating in a frequency-selective Rayleigh fading channel. Numerical results demonstrate that the achievable user capacity gain may be as high as 64% at a bit error rate of 10?2, when the maximum AATD is sufficiently low.
