摘　　要：基于常用的散射环(ROS)、散射盘(DOS)和截短高斯分布(CGS)信道模型,对不同波束之间的NLOS附加误差的相关性进行了分析,并根据分析结果,提出了一种基于天线子阵的定位方法。仿真结果表明,与基于基站的定位方法相比,基于天线子阵的定位方法在抵抗NLOS附加误差的影响方面,具有明显的优势。On the basis of such popular scattering models as ROS, DOS and CGS models, the correlation between the NLOS excessive errors of different beams from a mobile station is investigated. A novel approach is proposed, which is based on antenna subarrays. The simulation result justifies its superiority to the conventional approaches in resistance to NLOS errors, which are based on BSs.
