摘　　要：智能天线系统实现了同道在同小区的重用,其空域波束分配可以有效抑制同道干扰;信道分配可以充分结合其他信道资源。在Matlab系统级仿真中,充分利用定时器的特性,真实地建立移动台和基站之间在线服务的多线程通信仿真模型,对载频、时隙和码字中任一种或多种结合在空域位置形成的信道,提出基于载干比测量的动态信道分配策略,并对其进行了仿真研究和性能分析。仿真结果与理论分析吻合,同时得到一些有意义的参数。The same channel can be used in the same cell for smart antenna system,and its beam allocation can restrain the coherent interference efficiently,its channel allocation can combine other channel resources fully.Making full use of of the characteristics of timer,establishing multi-threading communication emulation model between MS and BS,proposing the optimum dynamic channel allocation strategy based on measuring carrier interference ratio,executing the emulation research and performance analysis for the channel composed of the frequency,time slot,code and the position beam in Matlab.Combining the simulated results with theoretical analysis,some valuable emulation parameters are obtained.
