When wireless multi-media information which includes speech, image, data and so on are transmitted, the difference in information rate, required quality as well as traffic performance should be taken into account. A wireless spread spectrum system can achieve a flexible balance of these differences because of the inherent asynchronous capability of CDMA.In this paper, we propose a wireless multi-media CDMA system based on a processing gain control in a dynamic traffic channel.According to the priority of each medium and channel measurement information, i.e. traffic, the optimal processing gain can be controlled by using Nonlinear Programming. Numerical results demonstrate that the proposed method possesses higher flexible capacity than TDMA in a dynamic multi-media traffic channel.
