Slepian-Based Two-Dimensional Estimation of Time-Frequency Variant MIMO-OFDM Channels

A linear channel estimator for multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) systems, based on a two-dimensional Slepian expansion, is presented. The estimator is meant to be part of an iterative receiver. We consider both estimation based on pilots only and o...
