摘要: 功率控制是S-CDMA-HFC系統(tǒng)上行信道的關鍵技術之一。對于初始接入CDMA終端,采用傳統(tǒng)的功率控制方法是不合理的。該文提出了一種初始接入改進功率控制算法,給出了吞吐量和接入時延性能仿真結果,并與傳統(tǒng)功率控制算法的性能進行了比較。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.
