Abstract

In this paper, we propose a novel approach for multiple input multiple output systems employing orthogonal space time block coding techniques considering independent but not necessarily identically distributed η–µ fading channels. We derive the probability density functions and cumulative distributions functions expressions for two different scenarios under (1) absolute SNR (AS) scheduling, and (2) threshold conditions. More specifically, under absolute SNR scheduling, PDF and CDF expressions are derived for independent non-identically distributed fading parameters, independent identically distributed average user SNRs (i.ni.d, i.i.d), and independent non-identically distributed fading parameters, and independent non-identically distributed average user SNRs (i.ni.d, i.ni.d). The derived expressions for PDF and CDF are used in obtaining average bit error rate and average channel capacity expressions for the proposed system. Both analytical and numerical results are shown to validate the obtained mathematical expressions.
