摘要
TD-SCDMA集群通信系统可以承载不同类型的集群多媒体业务,并能够为用户提供服务质量(QoS)保证。集群小区使用宏分集技术可以有效地克服大尺度衰落,保证信号质量。本文提出一种二基站宏分集方法,旨在对处在小区边缘的移动台进行信号的最大比合并,保证边缘小区用户的信号质量,同时降低传统宏分集对所有信号进行合并而增加的复杂度,且调整参与宏分集的基站,提高系统的前向容量。
TD-SCDMA trunking communication system can provide users with different types of multimedia services based on trunking system,and guarantee users＇ quality of service（QoS）.Trunking communication system using macrodiversity technique can effectively overcome the large scale of fading and ensure the quality of signal.This paper presents a method of macrodiversity based on two base stations,only the mobile station located at the edge of cell will use the maximum ratio combining algorithm,to ensure signal＇s quality of users located at the edge of cell,while reducing complexity of traditional macrodiversity algorithm because of all the signals combined,then adjust base stations,improve the forward-link capacity.
