Abstract

Abstract:

An optimal Joint MMSE decision feedback equalization (DFE) aided transceiver of amplify-and-forward (AF) relay-assisted MIMO systems is designed. Specifically, the linear processing matrix at the base station, the linear weighting matrix at the relay station and the nonlinear receiver consisting of the feedforward processing matrix and feedback processing matrix at the mobile station are jointly designed using the criteria of the minimum mean square error (MMSE). Compared with the existing joint linear MMSE benchmarker transceiver, for the BER of less than 10-3, our joint MMSE DFE transceiver has a performance gain of over 10dB.

Key words: multiple input multiple output, relay, amplify-and-forward, minimum mean square error, decision feedback equalization
