Abstract
- In this article, macro-diversity structure with macro-diversity selection combining (SC) receiver and two micro-diversity SC receivers operating over correlated shadowed multipath fading channel are analysed. Received signal is subjected simultaneously to α–µshort-term fading and gamma long-term fading (shadowing) resulting in system performance degradation. Macro-diversity SC receiver aims to reduce gamma shadowing effect while micro-diversity SC receivers aim to mitigate α–μ small-scale multipath fading effects. Useful infinite series expressions for the second-order statistical measure such as level crossing rate (LCR) of macro-diversity SC receiver output signal is efficiently derived. Numerical results are presented to examine the influence of various gamma shadowing and α–µmultipath fading parameters on LCR of the proposed system. [ABSTRACT FROM PUBLISHER]
