a Line of Sight path is introduced into the Rayleigh fading environment, the fading becomes a Ricean or Rice-distributed fading. In this paper, a review about the fading in the mobile environment is discussed followed the performance analysis of Rician fading channels in Minimum Shift Keying modulation scheme and Gaussian Minimum Shift Keying modulation scheme.

Ability of the Rician model to describe fading in wireless communications is the reason to derive infinity-series representations for both the probability density function (PDF) and the cumulative distribution function (CDF) of output signal-to-interference ratio (SIR) at the dual SC receiver over correlated Rician fading channels in the presence of correlated Rayleigh distributed cochannel Moreover, the Rician model includes both the unfaded Gaussian channel and the Rayleigh fading channel as two special cases. Hence, results obtained for this model provide a unifying perspective.
This paper is a study of BER performance of Reed-Solomon Coded M-ary frequency shift keying (MFSK) under AWGN, multipath Rayleigh and Rician fading channels. Simulations were ….

a review on rayleigh and rician fading channels Rayleigh fading occurs when there are multiple indirect paths between the transmitter and receiver and no distinct dominant path, such as LOS path. An effort has been made to illustrate the performance comparison of the Rayleigh and Rician fading channel models by using MATLAB simulation in terms of source velocity and outage probability. We have developed algorithms for the Rayleigh and Rician fading channels, which computes the envelop and outage probability. The parameters such as
