Abstract :
The paper developed a refined model for DS spread spectrum transmission over a Rician fading channel. A prevalent model in previous papers has been to group all signals received other than the dominant LOS path as interference. A new approach is taken, whereby some components of the multipath are included in the desired signal. An expression for the local-mean BER is derived from this model, and an analysis of BER as a function of the number of users is performed
