Near-far-effects on performance of DS/SS CDMA systems for personal communication networks
Ramjee Prasad, M.G. Jansen · 2002
The influence of near-far-effects on the performance of direct sequence spread spectrum code division multiple access (DS/SS CDMA) systems is investigated. A generalized model for the near-far-effect is developed by deriving the probability density function of the received mean power to be log-normal for a general spatial distribution of traffic controlled by a parameter defined as spatial shaping factor. The performance is measured in terms of the outage probability and throughput of the system.
