射频拉远

TD-SCDMA射频拉远技术应用及发展

Application and Development on Remote Radio Technique of TD - SCDMA

介绍了一种WCDMA基站时钟锁相的方法，尤其涉及WCDMA领域射频拉远模块中的时钟锁相技术。

A method of realizing clock phase-locked loop in WCDMA base station , especially in Radio Remote Unit ( RRU ), is introduced .

实际运用证明，该方法解决了OCXO长期稳定度不好的缺陷，并解决了射频拉远模块与上一级通信的同步问题。

The practice proves that the disadvantage of the bad long period stabilization of OCXO is overcome by this method , and the synchronization problem of RRU communicating with its upper is also solved .

它是基站的延伸，其射频拉远单元（RRU）可以放置在高楼、地铁、边远地区等信号盲区，对提高网络的覆盖能力起着重要的作用。

It is the extension device of the base station and can be placed in the signal blind zone , such as metro and remote area . It plays an important role in improving the network coverage .
