Résumé: In order to increase the spectral efficiency of modern digital communications, we consider more and more frequency selective channel which channel models requiering a growing processing complexity. In order to address this problem, we propose a new MMSE based equalization algorithm able to fully take advantage of the channel multipath estimation. To do so, we extend existing Expectation Propagation solutions with Decision Feedback to a Fractionally-Spaced receiver and we propose a new low-complexity implementation to stay competitive with existing solutions at the price of a channel estimation over a larger bandwidth. This leads to more than 2 dB Signal-to-Noise Ratio gain on tested 3GPP channels.
