Abstract

Instantaneous transmissions is a feature of wireless communication systems, which in turn results in some kind of interference since these transmissions use a common channel. This is phenomenon cannot be eliminated and hence many measures are taken to dampen its effect. Interference in this type of systems is a performance-limiting factor, where it increases the rate of dropped packets, which in turn causes a degradation in system quality. There are many causes for this kind of interference such cell overloading, a call in development in nearby cell or a base station very close that is using the frequency. The main two types of interference are Co-Channel Interference (CCI), and Adjacent Channel Interference (ACI).

In this paper these interferences effect on the performance of a wireless communication system over AWGN channel is investigated using the M-ary-PSK modulation scheme. This investigation covers the effect on Bit Error Rate (BER) and power spectra density of the transmitted signal in an addition to that the constellation diagram of the modulated and demodulated signals. The obtained results indicated that these interference signals have some effect on M-ary PSK modulation technique. The sternness of the effect depends on the modulation level i.e. the higher the level the more severe is effect.
