高速数据率(HDR)的功率控制技术

The Power Control Technology in High Data Rate (HDR) System

HDR(high:data rate,高速数据率)是面向CDMA2000所开发的高速无线接入技术,它可以在以 传输电话语音为主的通道以外,引进可以满足高速数据通信需求的技术。在HOR系统中,由于前向功率 恒定,不存在功率控制的问题。功率控制主要指的是反向功率控制,包括开环功率估计和闭环功率校正。 本文集中对HDR系统里面的信道系统、反向功率控制、功率校正等几个关键技术进行了深入的研究。

HDR(high data rate)is a high rate wireless access technology in CDMA2000 system, it can satisfy the need for higher data rate communications out of the voice channel. In HDR system , forward power control is not the key factor because of its invariableness; So Reverse Power control, include open-loop power adjust and closed- loop power correction, is the focus of our study. Some key problem about channel system,reverse power control,power correction and so on is the emphasis of the paper.
