Second order statistics of selection combining receiver over κ-μ Fading channels subject to co-channel interferences

Abstract

Radio propagation performances in interference-limited faded environment are studied in this paper. Selection combining (SC) based on signal-to-interference ratio (SIR) over-fading channels is performed. Probability density function (PDF) and cumulative distribution function (CDF) of the received SIR are determined. Based on the results obtained for PDF and CDF, infinite-series expressions are derived for the output level crossing rate (LCR) and average fade duration (AFD). These second order statistical measures are regarded as necessary for supporting technical documentation in every radio communication link design. Influences of various system parameters such as fading severity and the number of co-channel interferences affecting these measures are graphically presented and discussed. © 2012 American Geophysical Union.
