Abstract
This paper investigates improvement of the radiation pattern design of the transmitting array antenna beamforming and transmission power control (TPC) for the forward link of DS-CDMA/FDD system. Optimum transmission beamforming and power can be derived with the information of the propagation channel of the forward link in order to improve user capacity. It is assumed that a channel is static, all mobile stations (MSs) report measured channel characteristics to a base station (BS) and that controls received SIRs of all MSs by using this information. Then, the optimum control of transmitting beam pattern based on linear goal programming is proposed to improve user capacity.
