摘要
分析了TD-SCDMA系统中引入智能天线后空分信道的分配问题,根据空间角度相近且与基站之间的距离相差悬殊的用户使用不同的传统信道的准则,讨论了一种高效的基于信干比的空分信道分配搜索算法,用于解决传统信道复用中的组合寻优问题。最后针对该搜索算法进行仿真,分析结论并说明系统性能的改善。
This paper analyses the channel allocation in TD-SCDMA system associating with the smart antenna technology, according to the channel select rule that the different users having tHe approximative AOA and the different distance with the BS use different channel, discusses an efficient search algorithm for the spatial channel allocation based on C/I, and obtain the optimum channel allocation effects with the traditional physical channel. At last, this paper bases on the search algorithm, has some simulations and analyses the valuable conclusions.
