Equalization design for dispersive MIMO channels subject to channel variability

Multiple-input multiple-output (MIMO) equalizers combat the large amount of intersymbol interference and crosstalk generated in high-speed communication over dispersive MIMO channels. Unfortunately, fully adjusting these equalizers to the specific channel could induce intolerably large complexity. This contribution proposes an equalization strategy in which (part of) the equalizers are fixed and only depend on the channel statistics instead of the specific channel. The numerical results confirm that a hybrid strategy could indeed be a practical lowcomplexity alternative to the fully adjustable equalizers.
