Analysis of characteristics and development of TD - SCDMA system
CUI Rui, GUO Gang（Radio Engineering Department of Southeast University,Nanjing 210096,China）
Abstract:
As a standard of 3G technology proposed by China, TD - SCDMA is also one of the three main standards certificated by ITU. This paper simply introduces the key technologies applied in TD- SCDMA, such as joint detection, smart antenna, dynamic channel allocation, uphnk synchronization, relay handover, etc. Characteristics and development of the enhanced technology in standard evolution, like HSDPA, HSUPA, is discussed amply. This article also analyzes the development of TD - SCDMA technology. Finally it expresses the expectation of future TD - SCDMA industry.[著者文摘]
Key words:
