Abstract

A method for selecting the order in which the users are detected in communication systems employing adaptive successive decision feedback multiuser detection is proposed. Systems employing channel coding without the assumption of perfect decision feedback are analyzed. The method is based on the Mean Squared Error (MSE) measurements during a training period for each user. The analysis shows that the method delivers BER performance improvement relative to other previously proposed ordering methods.
