Outage Probability of SSC Receivers in Correlated Rayleigh Fading Channel with Multiple Cochannel Interferers

摘要

In the cellular mobile terrestrial and satellite communication systems, increasing of spectral efficiency is one of the main design goals. In such systems, signals from two or more channels and different locations operate at the same frequency interfere due to frequency reuse. This will result in cochannel interference as a general distortion in the performance of wireless communication [1, 2]. So, it is important to analyse how the interference affects well-accepted criteria of performance of wireless systems, such as outage probability, in order to implement practical system which satisfies predetermined minimum performance levels [3]. In addition to interference, fading is also a major obstacle in a mobile wireless environment, by introducing random amplitude and phase distortion to the transmitted signal [2]. An efficient technique to diminish the bad influences of fading and co channel interference is space diversity reception (analyses are presented in [4-5]). The principle of space diversity reception is to provide the receiver with multiple faded replicas of the same information-bearing signal. The goal is to upgrade transmission reliability without increasing transmission power and bandwidth, as well as to increase channel capacity.
