WCDMA闭环功率控制的研究

Study on the WCDMA Closed Loop Power Control

本文针对第三代移动通信系统ＷＣＤＭＡ方案，提出了功率控制中的信噪比的测量算法及修正曲线；并在Ｍ１２２５多径衰落信道下，以用最低信噪比达到相同通信误码率为准则，对闭环功控中的功率调整步长进行了优化仿真。

An algorithm and a correction function for calculating SIR are introduced in WCDMA, the 3^(rd) generation mobile communication system. Simulation of optimized power adjusted step △ SIR in the process of the closed loop power control in M1225 multi-path fading channel is conducted based on the criterion that lower SIR is better than higher SIR at the same Bite Error Rate.
