摘要

针对码分多址(CDMA)系统，提出了一种改进的二阶功率控制(ISOPC)算法。ISOPC使用当前和以前的功率水平进行功率更新，具有较快的收敛速度。对可行系统进行了收敛性分析，给出了ISOPC收敛的条件。然后在DS-CDMA系统中对ISOPC算法进行了仿真。结果表明，与SOPC算法相比，新算法具有更快的收敛速度。

An improved second-order power control iterative algorithm

The paper proposes an improved second-order power control (ISOPC) algorithm for code division multiple access (CDMA) systems. The ISOPC uses current and previous power levels for power updates and it has fast convergence speed. Convergence analysis is performed and the condition of ISOPC convergence is provided for feasible systems. The ISOPC algorithm is then simulated in a DS-CDMA system. The results indicate that the new algorithm has faster convergence speed compared to the SOPC algorithm.
