Base Station and User Positioning Method Under Scattered Beam

中文摘要英文摘要

针对通信系统中基站位置与朝向存在误差导致定位性能下降的问题,提出了一种基站与用户定位的协同优化方法.该方法在离散波束特性条件下,构建静动分离的联合定位模型,引入箱粒子滤波(Box Particle Filter,BPF),结合区间分析理论,并设计重采样机制以增强粒子多样性,有效抑制角度量测的非高斯误差.对不同基站初始误差及用户遮挡条件开展仿真分析,结果表明该方法在定位精度方面优于基于高斯假设的卡尔曼滤波,能够有效修正基站初始信息误差并保持较高稳定性,为离散波束环境下高精度定位系统的设计与实现提供了参考.

To address the degradation of positioning performance caused by errors in base station location and orientation in communication systems,a cooperative optimization method for base station and user positioning is proposed.Under discrete beam characteristics,a joint positioning model with static-dynamic separation is constructed,in which the Box Particle Filter(BPF)is introduced in combination with interval analysis theory,and a resampling mechanism is designed to enhance particle diversity,thereby effectively suppressing the non-Gaussian errors in angle measurements.Simulation analyses under different initial base station errors and user occlusion conditions demonstrate that the proposed method outperforms Gaussian-assumption-based Kalman filtering in positioning accuracy,effectively corrects initial base station information errors,and maintains high stability.This study provides a reference for the design and implementation of high-precision positioning systems in discrete beam environments.
