摘要 该文在分析TD-SCDMA系统无线资源管理机制的基础上,对该系统的动态信道分配算法进行研究。首先对现有的TDD-CDMA系统中的各种动态信道分配算法进行分类总结和分析比较,并在此基础了给出针对TD-SCDMA系统的慢速信道分配算法、快速信道分配算法以及考虑空间分布信息的信道分配方案,阐明了各自的特点和适用范围。研究了在TDD CDMA系统中如何进一步提高信道利用率的问题。 In this paper,we systematic discuss the dynamic channel assignment algorithms base on the TD-SCDMA system radio resource management strategy.We first summarize and compare the exiting dynamic channel assignment methods in TDD-CDMA system.Base on the TD-SCDMA system,the slow DCA algorithm,fast DCA algorithm and space distributing DCA algorithm are proposed,and their fea-tures and applicabilities are respectivelv illuminated.In this paper,the problem of how to improve the channel usability of TDD CDMA system is discussed.
