ABSTRACT

This paper present the comparative analysis of Rice and Two wave with Diffuse power (TWDP) fading models in terms of their probability density function (pdf) that describe small scale, local area fading experienced by narrow band wireless receivers in telecommunication. The paper also reviewed the basic method of generating the probability density function (pdf) for Rice and Two wave with Diffuse power (TWDP) model. Results of analysis from the plot of the probability density function (pdf ) against received envelope for worse distortion detection is also presented. Deduction from the graphical analysis on the nature of distortion observed at the presence of Strong Line of Sight (LOS) components in fading channels was also presented.

Keywords: Fading channel, Small scale effect, Random vector, probability density function, Multipath, Line of sight.
