| Abstract （English） |
In this paper we consider multiuser detection(MUD) scheme for direct sequence code division multipleaccess (DS/CDMA) systems. A change in group of ac-tive users in a mobile communication environment will de-grade the performance of MUD if it cannnot adapt quicklyto take into account the new set of interference parame-ters. We propose an optimal MUD scheme with referenceto the Bayes criterion in DS/CDMA systems which considerchange in groupe of active users. Computer simulation isused to obtain the efficiency of this scheme. |
