Performance of SC Receiver over Weibull Multipath Fading Channel
Authors: , , , ,
Abstract: The wireless communication system with dual selection combining (SC) diversity receiver operating over Weibull short term fading channel in the presence of cochannel interference affected to Weibull multipath fading, is considered in this paper. Weibull fading can be used to describe signal envelope variation in nonlinear fading environment. Cumulative distribution function and the level crossing rate of the ratio of two Weibull random variables are evaluated and these expressions are used for calculation the level crossing rate of dual SC receiver output signal envelope. These results can be availed for evaluation of the average fade duration of proposed communication system. The series in derived expressions rapidly converge for every values of fading parameters. The influence of Weibull fading parameter on level crossing rate is analyzed and studied.
