One of the major features of the WCDMA system of the third generation mobile communication system is its unique channel coding multiplexing scheme, which is the basis for supporting multimedia service transmission and one of the important differences from the second generation mobile communication system. Which realizes the bearer for various services with different rates and QoS requirements, but also greatly increases the system complexity and introduces a long processing delay.This paper elaborates the structural flow of this solution and analyzes the complexity of its implementation Based on this, a new algorithm is proposed, which uses the idea of moving data based on address calculation, which greatly simplifies the system and achieves much smaller storage capacity and processing delay than the direct algorithm and realizes WCDMA The entire encoding multiplexing scheme
