Title: Space-time processing for smart antennas in advanced receivers for the user terminal in 3G WCDMA systems
Author: Cardoso, FACM

Abstract: An adaptive multi-target space-time downlink receiver for user terminals of WCDMA systems under soft handoff is presented. The receiver consists of M antennas and K array processors, each one followed by a chip-rate equalizer and a despreader. The resulting K signals are combined in an "adaptive ratio combiner" which is updated by pilot common channel information in UTRA-FDD systems. All the structure in the FDD WCDMA downlink signal is exploited for improved performance. Simulation results for a stationary channel and for COST 259 channel models, for vehicle speed of 50 km/h, are presented.
