Behavioral Analysis of Wireless Channel Under Small-Scale Fading

Abstract

The demand for wireless communication has grown in recent years due to increase use of mobile services. The wireless communication channel constitutes the basic physical link established in the transmitter and the receiver. It is the challenging situation to model any wireless channel for radio wave propagation over tough geographical terrain like hilly areas, sea surface, mountains, etc. Channel modeling is one of the most fundamental aspects for study of optimization and design of transmitter and receiver. The operating environment factors like fading, multipath propagation, types of geographical areas limit the performance of wireless communication system. In this paper, wireless channel is modeled by randomly time-variant linear systems. The behavioral analysis of the channel model is performed for both the Rayleigh and Rician fading channels in terms of error probability, and it is shown that in small-scale fading, the Rayleigh fading can be preferred over Rician fading due to high SNR.
