Performance evaluation of Rayleigh and Rician Fading Channelsusing M-DPSK Modulation Scheme in Simulink Environment

摘要

The Computation of Bit Error Rate is a mandatory requirement for the analysis of multipath fading channels in any modulation scheme .Fading is nothing but the attenuation in signal strength when it is obtained at the receiver side and it is broadly classified into two types as fast fading and slow fading. If a line of Sight exists between the transmitter and receiver then Rician fading is modelled and in the absence of a line of Sight path Rayleigh fading can be modelled. The multipath intensity profile of a mobile radio channel depends critically on the type of terrain. The Performance comparison of the Rayleigh and Rician Fading channels in Differential Phase Shift Keying modulation using Simulink tool is dealt in this paper
