The problem of multiuser detection in multipath CDMA channels with receiver antenna array is considered. In particular, blind adaptive space-time multiuser detection techniques are developed, which requires prior knowledge of only the spreading waveform and the timing of the desired user???s signal. Single-user-based space-time processing methods are also considered and are compared with the multiuser approach. It is seen that the proposed multiuser space-time processing techniques offer substantial performance gains over the single-user-based methods, especially in a near-far situation.
