Abstract: Power control and rate allocation are two fundamental issues for improving the spectrum efficiency of downlink transmission for wireless multimedia communications. Downlink beamforming, on the other hand, can be used to suppress stronger interference induced by high rate users, thereby improving the system performance. In this paper, we present a joint downlink beamforming, power control and rate allocation technique suitable for DS-CDMA systems with multimedia services. To simplify the computational complexity, a practical rate allocation algorithm is also proposed. Computer simulation results are given to evaluate downlink capacity of DS-CDMA systems using base station antenna and the new algorithm proposed in this paper.
