例如卫星射频信号承载了时钟信号， 基站 300中的信号流向和各模块工作方式可以 是：
卫星天线 311接收卫星射频信号并通过馈线输出至适配器 315; 微波传输天线 313接 收微波射频信号并通过馈线输出至微波室外单元 314，微波室外单元 314对该微波射频信 号进行变频处理得到微波中频信号， 微波室外单元 314输出该微波中频信号至适配器 315。 适配器 315耦合该卫星射频信号和微波中频信号， 并将卫星射频信号和微波中频信 号的耦合信号输出至基站室内装置 320的微波室内单元 323。 微波室内单元 323的微波中 频模块 3231接收该卫星射频信号和微波中频信号的耦合信号， 分离该耦合信号中的卫星 射频信号和微波中频信号， 将分离出的卫星射频信号输出至卫星信号处理模块 100， 卫 星信号处理模块 100解码处理接收到的卫星射频信号得到时钟信号， 将时钟信号提供给 时钟模块 3234。时钟模块 3234利用该时钟信号对其时钟进行校准，并对微波室内单元 323 的其它模块进行时钟控制。微波中频模块 3231还将分离出的微波中频信号转换成微波基 带信号， 并将该微波基带信号输出至微波基带模块 3232; 微波基带模块 3232在时钟模块 3234的时钟控制下， 对该微波基带信号进行基带业务处理得到相应的微波业务信号； 业 务接口模块 3233将微波基带模块 3232处理得到的微波业务信号进行对应的格式转换， 并 将转换格式后的微波业务信号输出至基带模块 322， 可以理解， 由于时钟模块 3234是利 用卫星信号处理模块 100解码处理接收到的卫星射频信号得到时钟信号对其时钟进行校 准的， 而微波中频模块 3231、 微波基带模块 3232、 业务接口模块 3233等都是在时钟模块 3234的时钟控制下对微波信号进行处理的， 因此基带模块 322接收到的微波业务信号的 时钟与卫星是同步的。基带模块 322可以从来自微波室内单元 323的微波业务信号中提取 时钟信号 （等同于卫星信号处理模块 100解码处理卫星射频信号得到的时钟信号） ， 利 用该时钟信号进行时钟校准和控制等。
由上可见， 本实施例中将卫星信号处理模块设置于基站室内装置的微波室内单元 中，卫星天线和微波传输天线的信号通过一路数据线路从基站室外装置传导至基站室内 装置， 简化了基站室外装置到基站室内装置的馈线布线， 同时还可以相对减少防雷模块 的数量， 有利于降低制造成本。
