Comparison of Analytic Inversion Techniques for Equalisation of Highly Frequency-Selective MIMO Systems
This paper discusses MIMO equalisers created by analytic inversion of a known frequency-selective MIMO channel. It considers inversion performed in the $z$-domain, time-domain using convolutional matrices, and the frequency-domain. It explains the criteria of these inversions and compares the performances in terms of MSE between the input and output to a concatenated channel-equaliser system through use of simulations, and puts these results into context in terms of computational cost.

Abstract

This paper discusses MIMO equalisers created by analytic inversion of a known frequency-selective MIMO channel. It considers inversion performed in the $z$-domain, time-domain using convolutional matrices, and the frequency-domain. It explains the criteria of these inversions and compares the performances in terms of MSE between the input and output to a concatenated channel-equaliser system through use of simulations, and puts these results into context in terms of computational cost.
