Abstract

This paper proposes a wireless multimedia CDMA system based on transmission power control. When we transmit multimedia information such as speech, image and data, differences in the information rate, traffic performance and required quality should be taken into account. The wireless CDMA system can achieve a flexible balance of these differences if the transmission power distribution is controlled using channel measurement information such as traffic. The optimal control of transmission power is derived by linear programming and nonlinear programming. Numerical results demonstrate that the proposed method can satisfy the required quality
