Second-order statistics of selection macro-diversity system operating over Gamma shadowed κ-μ fading channels

Abstract

In this article, infinite-series expressions for the second-order statistical measures of a macro-diversity structure operating over the Gamma shadowed -μ fading channels are provided. We have focused on MRC (maximal ratio combining) combining at each base station (micro-diversity), and selection combining (SC), based on output signal power values, between base stations (macro-diversity). Some numerical results of the system's level crossing rate and average fading duration are presented, in order to examine the influence of various parameters such as shadowing and fading severity and number of the diversity branches at the micro-combiners on concerned quantities.

Channel capacity of the macrodiversity SC system in the presence of kappa-mu fading and correlated slow gamma fading

“…In most cases, the slow fading is correlated. The signal envelope is variable due to the fast fading, and the power of signal envelope is variable due to the slow fading [4], [5].…”

“…In many papers [18], [19], [20], [21], statistical characteristics of the signal for macrodiversity systems are presented. For the considered system results have not been presented yet.…”

The LCR of wireless macrodiversity SSC receiver in the presence of gamma shadowed Kappa-Mu fading

“…MaD switch and stay (SSC) system with MiD selection combining (SC) as well as MaD SC system with MiD maximal ratio combining (MRC) or SC can be efficiently applied in composite fading environment to improve performances of wireless communication system as shown in( (Stefanović, 2015), , (Stefanović et al, 2016), (Panić et al, 2011), (Stamenović et al, 2014)). …”

Performance of Diversity System Output Signal in Mobile Cellular System in the Presence of α-μ Short Term Fading and Gamma Long Term Fading

“…The infinite-series expressions for the second-order statistical measures of macro-diversity structure operating over Gamma shadowed κ-μ fading channels is provided in [8]. The authors focused on maximal ratio combining (MRC) at each base station (micro-diversity), and SC combining, based on output signal power values, between base stations (macro-diversity).…”
