Slepian-based serial estimation of time-frequency variant channels for MIMO-OFDM systems

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

This paper proposes a low-complexity two dimensional channel estimator for MIMO-OFDM systems derived from a time-frequency variant channel estimator previously
proposed. The estimator exploits both time and frequency correlations of the wireless channel via use of Slepian-basis expansions. The computational saving comes from replacing a two-dimensional Slepian-basis expansion with two serially concatenated
one-dimensional Slepian-basis expansions. Performance in terms of Normalized Mean Square Error (NMSE) vs. Signal-to-Noise Ratio (SNR) have been analyzed via numerical
simulations and compared with the original estimator. The analysis of the performance takes into account the impact of both system and channel parameters.
