Receiver design of MIMO systems in a mixture of Gaussian noise and impulsive noise

In this paper, the receiver design of MIMO systems is performed in a mixture of Gaussian noise and impulsive noise modeled as a symmetric alpha stable process. Both spatial multiplexing systems (SM-systems) and diversity based systems are considered. The optimal receiver and several suboptimal receivers are developed and the related problems, such as performance and robustness, are discussed. Simulation shows that the proposed receivers can achieve much better performance than the traditional MIMO receivers in the mixed noise.
