Abstract

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
