0.背景随着3G业务竞争的日趋激烈,TD-SCDMA网络的不断建设与完善,基于BBU(基带处理单元)+RRU(射频拉远模块)形式的分布式基站已经成为室内信号覆盖的主要方式。3G网络大量使用分布式基站架构,RRU和BBU之间需要用光纤连接,一个BBU可以支持多个RRU。采用BBU+RRU多通道方案,可以很好地解决大型场馆的室内覆盖问题。与2G时期单纯的语音、较少的数据业务不同的是,TD-

Background With the increasingly fierce competition in 3G services and continuous construction and improvement of TD-SCDMA networks, distributed base stations based on BBU (Baseband Processing Unit) + RRU (Radio Remote Unit) have become the main mode of indoor signal coverage . A large number of 3G networks use a distributed base station architecture. An optical fiber connection is required between the RRU and the BBU. One BBU can support multiple RRUs. The BBU + RRU multi-channel solution can solve the problem of indoor coverage in large stadiums. And 2G simple voice, less data service is different, TD-
