Abstract: For higher capacity of the multi-service hierarchical CDMA systems, this paper represents a compensation method of traditional power control method, which is based on the prediction of power adjusting and the confidence level. Simulation proves that it is better than traditional power control method, which reduces interrupt possibility by about 15%.

摘要： 针对传统功率控制算法在多业务分层CDMA系统中中断概率高、系统容量下降等问题，提出一套功率控制补偿方案。算法着眼于信道和业务动态变化的可靠程度(置信度)。通过对补偿算法仿真，证明该方案较传统方案降低了约15%的中断概率，提高了系统容量。
