根据宽带码分多址 (WCDMA)系统单小区功率分配算法有解的充要条件 ,得到速率与容量之间、服务质量与速率之间的定量换算关系 .利用可变比特速率业务的速率减少可以增加恒定比特速率业务和可变比特速率业务的容量 ,通过适当降低非特指服务质量业务的服务质量 (QoS)可以提高可变比特速率业务的速率 .数值计算结果表明 :业务速率、服务质量和系统容量之间存在着互换关系 ,根据不同业务的性能要求 ,可以通过改变业务参数来提高系统的适应性、资源利用率和服务质量 .
According to the single-cell power allocation algorithm in WCDMA system, a sufficient and necessary condition exists for the solution to obtain the quantitative conversion relation between the rate and the capacity, the quality of service and the rate. The rate reduction using the variable bit rate service can Increasing the capacity of constant bit rate service and variable bit rate service can improve the rate of variable bit rate service by properly reducing the quality of service (QoS) of unspecified quality of service.The numerical results show that the service rate, quality of service and system According to the performance requirements of different services, the system adaptability, resource utilization rate and service quality can be improved by changing the service parameters.
