A novel wideband beamforming technique for cellular CDMA systems is presented. The proposed algorithm asymptotically provides the optimum combination of space-time samples for maximizing the SINR for the Signal with the Desired Code (SDC) by canceling strong Multi-User Access Interference (MUAI) and optimally combining the multipath. In contrast to previously proposed techniques, bit synchronization for the SDC is not required. The algorithm presented herein asymptotically provides the respective time of arrivals of the multipaths within a bit period, and the optimum beamformers for extracting each multipath. Subsequently space-time weights for combining the fingers across both space and time while canceling the MUAIs are found.
