摘要: In a CDMA data communication system capable of variable rate transmission, utilization beam switching techniques decreases the average interference caused by transmissions base station to subscriber stations within cell, and in neighboring cells. Base utilize multiple transmit antennas, each transmitting signals at controlled amplitudes phases, form signal corresponding sector divisions. Data reference are transmitted along division beams that alternate according fixed time slots order increase capacity rates maximizing carrier-to-interference ratios (C/I) measured stations.
