N2 - Impulsive, non-Gaussian noise is prevalent in wireless environments. We adopt an impulsive noise model over multi-input-multioutput (MIMO) channels and discuss receiver design and code design over MIMO channels with impulsive noise. We derive the code design criterion for the so-called genie-aided receiver and suboptimal receiver, both of which yield criteria identical to [11] when the noise is not impulsive. We propose a maximum a posteriori (MAP) receiver, whose performance can be tightly lower bounded by the genie-aided receiver. We simplify the optimal MAP receiver by an approximation and show that for all cases of practical interest, only 2 terms in the approximation is enough to get near-optimal performance.
