摘　　要：针对传统的多基站定位容易引起通话质量干扰问题,提出了在TD-SCDMA蜂窝系统中,仅采用单个基站定位的混合定位算法(HPSR,hybrid positioning scheme with RSS)。在该算法中,设计了一种新的冗余RSS数据融合模型(RDFM,RSS data fusion model)以消除非视距(NLOS,non-line-of-sight)误差,提高定位精度,并从理论推导证明了此模型的有效性。给出了运用在实际中的定位流程图,并进行了仿真验证,仿真结果表明,HPSR同时提高了TOA/AOA算法的稳定度和精确度。A novel single BS positioning scheme for TD-SCDMA systems was proposed called HPSR （hybrid positioning scheme with RSS）, by which the interference caused by multilateral positioning systems is avoided. Moreover, one RSS data fusion model is established to eliminate NLOS error and improve the accuracy of positioning. A specific flowchart to be put into practice is given and simulated. The results indicate that compared with present TOA/AOA, the proposed scheme is more stable and accurate .
