Performance Comparison of OT-MRC and MEC-GSC with dual branches over Correlated Nakagami-m Fading Channels

In this paper we investigate the performance of output threshold maximum ratio combining (OT-MRC) and minimum estimation and combining generalized selection combining (MEC-GSC) scheme with dual branches over correlated Nakagami-m fading channels. The OT-MRC and MEC-GSC schemes select the minimum number of diversity branches such that their combined received signal-to-noise ratio (SNR) is above a certain pre-determined target SNR that is set to meet the required quality of service (QoS). Based on the joint probability density function (PDF) and moment generating function (MGF) of the combined received SNR, the performance comparisons of dual OT-MRC and MEC-GSC over correlated Nakagami-m fading channels are presented.
