The research on suboptimal MUD strategies begins with techniques for detection of un-coded CDMA systems =-=[2]-=-. It is shown that most of the suboptimal MUDs have good performance given a small number of users. However, the performance of suboptimal MUDs for uncoded DS-CDMA systems is subject to system constra... |
