摘　　要：针对提出的业务模型,分析了多业务DS-CDMA系统中各类业务的QoS性能如平均延时、吞吐量及比特差错率等与各类业务的处理增益和功率分配的关系,提出了一种适用于两类业务(一类实时、一类可靠)的优化处理增益和功率分配算法,数据结果表明优化算法可以在保证两类业务QOS的同时提高系统容量及可靠业务的吞吐量。Based on the proposed traffic model, the QOS measures of multiple class of services in DS-CDMA systems, such as average delay, average throughput and bit error rate are formulated. An optimal processing gain and power allocation algorithm for two class of services (one real-time, the other reliable) is presented, the numerical results show that QOS requirements of both service classes can be satisfied by the optimal algorithm, meanwhile, the system capacity and throughput of the reliable service are enlarged.
