In this letter, we analyze the error performance of a mobile communication system with microdiversity and macrodiversity reception in gamma‐shadowed Rician fading channels for a binary differential phase‐shift keying modulation scheme. Analytical expressions for the probability density function (PDF) and moment‐generating function (MGF) are derived. The average bit error probability can be calculated by averaging the conditional bit error probability over the PDF or using the MGF‐based approach. Numerical results are graphically presented to show the effects of macrodiversity, correlation, number of diversity branches, and severity of both fading and shadowing.
In this paper wireless communication system with dual branch selection
combining (SC) diversity receiver operating over k-? multipath fading
environment is considered. Closed form expressions for average level
crossing rate of SC receiver output signal envelope and average fade
duration of proposed system are evaluated. Numerical results are presented
graphically to show the influence of Rican factor k and fading severity ? on
average level crossing rate and average fade duration.
