| Abstract: | Blind multiuser detection is the key of 3G mobile communication.In this paper,we analyze the performances of Kalman fi lter algorithm of blind multiuser detection in DS-CDMA communication system.And the algorithm of Kalman algorithm combined with subspace blind multiuser detection is proposed,the simulation of computer shows it is superior to Kalman algorithm in the convergence performance. |
