空间信道模型描述了多径分量的到达角度和到达时延的相关数据信息,在设置天线阵列的无线通信系统的性能评估方面作用显著。所有现存的几何模型基本上都是二维的,如离散均匀模型[1-2]、椭圆散射模型[3]、圆形散射模型(CSM)[4]、高斯散射密度模型[5]、高斯AOA模型[6]等,上述模型均认为信号传输发生在连接发射和接收天线顶...

Hii, I have setup a positioning example using 3x BRD4191A boards connected to a Raspberry Pi 5 to run the locator example and a raspberry pi 5 as MQTT broker and the central. I have observed there is heavy deviation in data. Even if I keep the device at a static location. The dot ...
Hello all, I am currently using the demo "bgt60tr13c," and referring to the example code "range-angle-map.py, what I understand is it uses a beamforming technique to determine the azimuth and elevation angle. I have the following question: 1. As quoted in RFS SDK documentation "I...
I have angle of arrival results (rays coming from different angles with different power), the results contain the azimuth angles with their correponding received power, i want to represent each incoming ray by a line that originates from center of the plot without being connected to the other...
(BS) in the azimuth planeand elevation plane are derived respectively .Moreover ,closed‐form expressions for propagation path de‐lays and trivariate joint PDFs of the time of arrival (TOA) seen at the MS are investigated .The observedtheoretical results are compared with some presented 2‐D ...

In this paper, we adopt the Levenberg-Marquardt (LM) algorithm to implement the nonlinear multivariable optimization for azimuth/elevation angle-of-arrival (AOA) estimation based on the Capon beamforming algorithm. The formulation is based on the fact that the cost function of the Capon algorithm ...
Elevation and azimuth angles are unstable because of the influence of noise. In this paper, a Self-Learning Mean Optimization Filter (SLMOF) is proposed. The goal of SLMOF is to find the optimal elevation and azimuth angles as a way to improve the Bluetooth 5.1 AoA indoor positioning ...
