摘要
This paper proposes a wireless multimedia code division multiple access (CDMA) system based on transmission power control, When we transmit multimedia information (i.e., speech, image, and data), differences in information rate, traffic performance, and required quality should be taken into account, The wireless CDMA system can achieve a flexible balance if transmission power distribution is controlled by using channel measurement information, i.e., traffic, In this paper, 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.
