Abstract

"The major purpose of this contribution is to analyze a VSG-WCDMA (variable spreading gain wideband code division multiple access) system in the reverse link with multiple rate services. The multi-rate VSG technique can be implemented with different quality of service (QoS) targets and distinct activity factors. A system-level simulation approach is employed where we consider three smart antenna strategies: switched fixed beams, spatial matched filter and fully adaptive antennas. Gains in average signal-to-interference ratio (SIR) are then evaluated. Distinct user scenarios are defined based on bit rate and user spatial distribution. The system-level model takes into account imperfect power control, multiple cellular environment and a realistic antenna element radiation pattern."
