摘要:

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的可能性。根据2G室内分布系统的现状和TD-SCDMA技术特点,提出了TD-SCDMA室内分布系统末端合路的建设方案,实现TD-SCDMA系统与现有的2G/3G室内分布系统的共享。

关键词: TD-SCDMA, 室内分布, 共享, 功率匹配, 末端合路

Abstract:

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 the end-multiplex resolving scheme, to sharing 2G indoor distributed system.

Key words: TD-SCDMA, indoor distributed system, share, power matching, end-multiplex
