Abstract :
A finite-length optimized-delay multi-input multi-output mean-square-error decision-feedback equalizer for space-time block-coded transmission over multipath fading channels is presented. Alamouti´s space-time block code with 2 transmit and 2 receive antenna on a typical urban EDGE channel is taken as a case study. We propose a combined equalization and decoding scheme under the constraint of linear processing complexity (no trellis search) at the receiver. Performance comparisons are made with the single-transmit/single-receive antenna case and the case of multi-input multi-output feedforward linear equalization only with no decision feedback
