TD-SCDMA综合分布系统改造方案

Rebuild Scheme Analysis of TD-SCDMA Indoor Distributed System

通过对现有通信系统的信号源、分布系统及空间传输损耗的讨论,本文分析了TD-SCDMA与现有室内分布系统共享时存在的功率匹配问题。结合2G室内分布系统的现状和TD-SCDMA技术特点,分析了微型、小型、中型和大型4种典型2G分布系统的TD-SCDMA改造方案。

The paper discusses the TD-SCDMA indoor distributed system,including signal source,distributed system and radio wave transmission losses.According to the peculiarity of TD-SCDMA technology and the 2G current distributed system situation,the paper concludes four type rebuild modes,including mini,small,middle and big indoor distributed systems.
