Description: An effective approach to increase system capacity is to integrate beamforming (spatial processing) and multiuser detection (temporal processing). However, it is impractical due to the high computational costs. The first part of the thesis introduces the Joint Domain Localized (JDL) adaptive processing which processes spatial and temporal data within a localized region. This new processor is developed for single-cell uplink CDMA systems with multiple receive antennas. The simulations show that this approach is more effective than other reduced-rank schemes in suppressing interference at significantly lower computational costs and faster convergence rate in terms of the number of training symbols. With short training sequences, it even outperforms the fully optimal filter. The second part of this thesis introduces a variant of the JDL processor that combines JDL processing and the zero forcing technique (JDL-Z) for multi-cell uplink CDMA systems which achieves better performance and faster convergence rate than the JDL processor.
