| Abstract: | The problem of multiuser detection for direct-sequence code division multiple access (DS-CDMS) communication system is considered. A blind multiuser detection algorithm is proposed based on independent component analysis (ICA). Multiple access interference (MAI) can be suppressed based on the proposed algorithm. The advantage of the proposed algorithm is that it is able to perform multiuser detection without the users' spreading codes. Simulation results demonstrate that the proposed method offers high performance. |
