摘　　要：针对TD-SCDMA系统现有慢速动态信道分配算法的不足,提出了一种热点小区簇衍生算法。该算法通过热点小区不断衍生的方式形成多小区系统模型,解决了热点小区簇的判别和扩展问题,提高了系统容量。仿真结果表明:热点小区簇衍生算法适用于不同的业务分布模型,相对于热点小区算法,系统资源利用率提高了3.8%。Aiming at overcoming the shortages of the current slow dynamic channel allocation algorithm in TD-SCDMA system, hot cell clusters deriving algorithm was proposed. The algorithm constituted a multi-cell system model through the way that the hot cells were continuously derived to resolve the identification and expansion problem of the hot cell clusters. As the result, system capacity is increased. The simulation results show that, the hot cell clusters deriving algo- rithm can adapt to different service distribution models well. Compared to the hot cell algorithm, the system resource utilization is increased by 3.8 percent.
