HSDPA关键技术及信道特性研究

Research on the Key Techniques and Channel Structure of HSDPA

HSDPA即高速下行链路分组接入技术,它是3GPPW-CDMAR5协议中提出的一种标准技术。本文首先介绍了HSDPA的关键技术,然后对HSDPA的信道特性进行了详细分析,最后对HSDPA的使用过程进行了研究。

High Speed Downlink Packet Acess （HSDPA） technology was standardized for 3GPP W-CDMA Release-5. Firstly this paper introduces an overview of the advanced techniques of HSDPA,and then analyses the channel characteristics elaborately.Finally it presents a brief research on the using process of HSDPA.
