  New approach for analysis and decoding MIMO signaling is developed for usual
model of nongaussion noise consists of background and impulsive noise named
epsilon - noise. It is shown that non-gaussion noise performance significantly
worse than gaussion ones. Stimulation results strengthen out theory. Robust in
statistical sense detection rule is suggested for such kind of noise features
much best robust detector performance than detector designed for Gaussian noise
in impulsive environment and modest margin in background noise. Proposed
algorithms performance are comparable with developed potential bound. Proposed
tool, is crucial issue for MIMO communication system design, since real noise
environment has impulsive character that contradict with wide used Gaussian
approach, so real MIMO performance much different for Gaussian a non-Gaussian
noise model.
