| 摘 要： | 功率控制是S-CDMA-HFC系统上行信道的关键技术之一。对于初始接入CDMA终端,采用传统的功率控制方法是不合理的。该文提出了一种初始接入改进功率控制算法,给出了吞吐量和接入时延性能仿真结果,并与传统功率控制算法的性能进行了比较。

| Abstract: | The power control is one of the key techniques of the upstream channel of the S-C'DMA-HFC system. It is unreasonable that the acquisition CDMA terminals employ the traditional power control methods. In this paper, an improved acquisition power control algorithm is proposed. The simulation results of the throughout and the access delay are given and the performance comparison between the improved algorithm and the traditional method is provided. |
