In multiple-input multiple-output (MIMO) systems, symbol error rate (SER) performance of Gamma shadowed Weibull multipath fading channel has not been investigated in existing literature. In this paper, MIMO system is realized with maximal ratio combining (MRC) technique that operates over Weibull-Gamma (WG) fading channel where WG forms a generic distribution. Higher order modulation like 16-phase shift keying (16-PSK) and 16quadrature amplitude modulation (16-QAM) are used with MIMO-MRC for the analysis of proposed system. Simulation and analytical results show that by increasing the values of fading parameters (β and m), SER performance can be improved. Also16-QAM gives better SER performance than 16-PSK.

In multiple-input multiple-output (MIMO) systems, spatial demultiplexing at the receiver has its own significance. Thus, several detection techniques have been investigated. There is a tradeoff between computational complexity and optimal performance in most of the detection techniques. One of the detection techniques which gives improved performance and acceptable level of complexity is ordered successive interference cancellation (OSIC) with minimum mean square error (MMSE). However, optimal performance can be achieved by maximum likelihood (ML) detection but at a higher complexity level. Therefore, MMSE-OSIC with candidates (OSIC
