Average LCR and AFD of Dual MRC and SC Diversity in Correlated Small-Scale Fading Channels

چکیده
In this paper, the performance of average level crossing rate (LCR) and average fade duration (AFD) of the output signal of the maximum ratio combining (MRC) and the selection combining (SC) with a dual-branch receiver was analyzed. We derived some of the expressions with average LCR and AFD for both MRC and SC schemes operating in the correlated fading channel. The channel model of the diversity branches are assumed characterized as correlated Nakagami-m statistics. The results from the numerical analysis indicate that the average LCR and AFD of MRC and SC schemes are significantly affected by the correlation between each branch when they are working in the correlated environments.

Wireless mobile communication system with selection combining (SC) diversity receiver is investigated in this paper. Received signal envelope experiences α-κ-μ short term fading resulting in system performance degradation.

This paper derives the second-order statistics of SC (selection combining) macrodiversity operating over the Gamma shadowed Nakagami-m fading channels. Macrodiversity system of SC type consists of two microdiversity systems and selection (switching) is based on their output signal power values. Each microdiversity system is of MRC (maximal ratio combining) type with arbitrary number of branches...

Probability density function (PDF), moments of signal and amount of fading (AF) at the output of macrodiversity system in closed form are obtained. Moreover, level crossing rate (LCR) of signal at output of macro diversity system is analytically derived and used to study average fade duration (AFD) of the proposed system. Dual maximal-ratio combining (MRC) is implemented at the micro level (sin...
