摘要: 為了克服CDMA移動(dòng)臺(tái)(MS)定位估計(jì)中面臨的遠(yuǎn)近效應(yīng)問(wèn)題,該文提出了一種在服務(wù)基站(BS)附近布置一種天線(xiàn)陣列,采用TSOA/AOA混合定位技術(shù)對(duì)MS進(jìn)行定位估計(jì)的方法,分析了采用不同定位法的GDOP分布, 并給出了相應(yīng)的TSOA/AOA混合定位算法。不同條件下的仿真結(jié)果表明,只要AOA測(cè)量值達(dá)到一定精度,采用這種方法就能對(duì)MS進(jìn)行準(zhǔn)確定位。Abstract: In order to overcome the near-far problem encountered in CDMA mobile location estimation, in this paper a mobile location method to utilize an antenna array and TSOA/AOA hybrid location technique is proposed, the GDOP distribution of different location methods are analyzed and TSOA/AOA hybrid location algorithm are provided. Simulation results under different condition show that as far as AOA measurements is relatively accurate, mobile can be exactly located by this method.
