SIR based LCR performance analysis of hybrid SC diversity reception in mobile wireless networks over composite fading channel

Abstract

The paper provides signal to interference (SIR) based second order performance analysis of hybrid diversity reception with macro level (MaL) selection combining (SC) diversity receiver and three micro level (MiL) dual branch SC diversity structures in correlated Gamma shadowed non-line-of-sight (NLOS) multipath fading environment. The infinite series expression for second order statistical measure such as average level crossing rate (LCR) is obtained, numerically presented and discussed regarding different system model parameters. Precisely, the effects of Gamma long term fading severity parameter of desired signal, Gamma long term fading severity parameter of co-channel interference (CCI), shadowing correlation parameter, average signal power of desired signal as well as average power of CCI on LCR are thoroughly examined.
