无线本地环(WLL)是一种无线接入系统,它用无线的方式代替了传统的铜线连接用户到本地交换机。介绍了一种用于宽带CDMAWLL系统的数字接收机。叙述了WLL的系统组成、网络结构、反向链路信道结构和反向中继接收机设计规范,并论述了代码捕获和代码跟踪模块的功能。接收机的运行时钟频率可达65.536MHz。
Wireless Local Loop (WLL) is a wireless access system that wirelessly replaces traditional copper cabling subscribers to a local switch. A digital receiver for a wideband CDMAWLL system is introduced. Describes the system components, network structure, reverse link channel structure and reverse relay receiver design specifications of WLL, and discusses the function of code capture and code tracking module. Receiver operating clock frequency of up to 65.536MHz.
