The presentation will introduce the basics of multiuser detection and conventional techniques of multiuser detection. The heuristic algorithms will be introduced and several heuristic algorithms including Genetic Algorithm, Particle Swarm, and Tabu search algorithms will be presented in some detail. Simulation results on some of these algorithms will be presented. It is shown that the noise enhancement found in the decorrelator detector is not present in the case of heuristic algorithms with the result that the performances of these algorithms are better than that of decorrelator detectors.
