摘要
宽带码分多址(WCDMA)是3G移动网络中的接入技术,文章主要讨论了WCDMA物理层无线接口的下行链路上,正交可变扩频因子(OVSF)编码的几种分配策略,对几种方案的优缺点进行了讨论,并针对RDA策略,提出了一些改进的想法。
Wideband Code Division Multiple Access(WCDMA) is the access technology in the 3G network,this article mainly studis several allocation strategies of Orthogonal Variable Spreading Factor Codes(OVSF) in downlink of WCDMA physicall wireless interface,the advantages and disadvantages of several schemes are discussed,and aiming the RDA strategy,we talk about some improved ideas.
