Multiuser detection for time synchronous ARGOS signals
Résumé
Multiuser detection has recently been a big challenge in the increase of the performance for a satellite communication system. In the previous studies on systems such as CDMA, researchers have derived general mathematical expressions to describe the system model. However, when it comes to specific system such as ARGOS system, solutions based on general expressions may no longer be valid and thus new mathematical derivations could be formulated. In this paper, we propose a new mathematical model for synchronous multiuser communication in ARGOS system and we analyse the performance of the optimum multiuser detector and some sub optimum techniques such as conventional, decorrelator, Minimum Mean Square Error, and successive interference cancellation detectors.
