MIMO scheme performance and detection in epsilon noise

A new approach to analyzing and decoding MIMO signaling has been developed for the regular model of non-Gaussion noise, consisting of background and impulse noise named ε-noise. It has been shown that non-Gaussion noise performance is significantly worse than Gaussion noise performance. Simulation results support the suggested theory. Robust in a statistical sense detection rule is suggested for such kind of noise, featuring a much better robust detector performance than the detector designed for Gaussian noise in an impulsive environment, but marginally less effective in background noise. The performance of the proposed approach is comparable with the developed potential bound. The proposed tool is a crucial issue for the MIMO communication system design, since a real noise environment has an impulsive character that contradicts the widely used Gaussian model. Therefore, the real MIMO performance for Gaussian and non-Gaussian noise models is entirely different.
