Abstract
This paper shows a detailed statistical characterization of a specific system configuration consisting of one multibranch maximal-ratio-combining (MRC) and one selection-combining (SC) micro-level base station, and SC back processing unit at macro level. Primarily, the scenario of the independent and identically distributed generalized-K fading channels is investigated. After that, the correlated branches at SC-based micro-level are assumed. The outage probability and the error probability performance for both cases are defined. According to the presented analytical analysis, numerical results are obtained. Also, the impact of the number of MRC and SC input branches, the impact of the fading/shadowing factor, the predefined outage threshold, the average signal-to-noise ratios and the correlation coefficient on the specified system performance is shown. Simulations validate the accuracy of the proposed analytical analysis.
