摘要

提出了一种分组交换时分双工直接序列扩频(DS-SS)通信系统，用于具有瑞利衰落特性的移动和无线室内CDMA通信。然后，为该系统提出了一种功率控制方法，该方法能够提供信道衰落状态的有效估计，并使用该信息自适应地控制上行链路发射功率，以使基站接收功率均衡。通过与典型室内通信系统参数的参考水平比较接收功率的分布，评估了该功率控制方案的性能

Power control in packet switched time division duplex direct sequence spread spectrum communications

A packet switched time-division duplex direct-sequence spread-spectrum (DS-SS) communication system is proposed for operation in mobile and wireless indoor CDMA communications with Rayleigh fading characteristics. A power control method is then proposed for this system capable of providing effective estimates of the fading state of the channel and using this information to adaptively control the uplink transmission power for equalized received power at the base station. The performance of this power control scheme is evaluated by examining the distribution of the received power compared to a reference level for typical indoor communication system parameters.<>
