Abstract

This paper investigates the channel capacity of direct sequence spread spectrum (DSSS) code division multiple access (CDMA) wireless mobile communication systems in Rayleigh distributed lognormal shadowed fading channels. The proposed model builds upon the former Jakes model deploying multiply-detected macroscopic (MDM) diversity reception combining to achieve enhanced data rates at lower bit error probabilities in shadowing environments. Capacity in terms of the number of users per cell is determined.
