Abstract :
We propose two reduced state versions of maximum likelihood multiuser detector (MLMD) for down-link connections in time division-code division multiple access (TD-CDMA) systems. Simulation results have shown that these algorithms perform substantially better than other widely used suboptimum detection techniques. Moreover, they have a computational complexity proportional to the number of users
