Abstract:

A remote antenna unit(RAU)selection model is presented, and two kinds of handoffs, intra-cell handoff(HO)and inter-cell HO, are defined in distributed mobile communications systems(DAS).After that, an inter-cell HO model is proposed, in which the average power of the active set(AS)is used to predict the position of the mobile station(MS).The total power of the AS and the handoff set(HOS)are utilized to determine whether an inter-cell HO is necessary.Furthermore, the relationship between HO parameters and performance metrics is studied in detail based on RAU selection.Simulation results show that both the intra-cell HO and the inter-cell HO can achieve perfect performance by appropriate settings of HO parameters.

首先给出了一种远端天线单元选择的分析模型, 并定义了分布式移动通信系统中2种类型的切换:小区内切换(intra-cell HO)和小区间切换(inter-cell HO);然后提出了一种小区间切换的模型, 该模型利用激活集的平均功率强度来预测移动台(MS)的位置, 通过比较激活集和切换集的总功率, 来判断移动台是否需要进行一次越区切换.此外, 在RAU选择的基础上, 详细分析了2种切换方式中切换参数和切换性能指标之间的关系.仿真结果表明, 通过合理地选择切换参数, 2种切换方式都能够取得良好的性能.
