Abstract

A multi-Rician fading model for radio communication systems in which the received signal consists of a finite number of specular components in addition to a diffuse component is presented. The probability density function of the envelope of the received signal is obtained from basic principles, and it is shown that, in some cases, the multi-Rician distribution gives fading which is deeper than Rayleigh fading. It is also shown that this general model includes the Rayleigh and Rician fading distributions as special cases. The use of spatial selection diversity is considered to combat the effects of fading, and the performance of two types of selection diversity receivers in the presence of multi-Rician fading is obtained for various cases of practical interest
