摘要

在可见光通信(VLC)室内定位领域中, LED半功率角辐射范围内信号强度大, 运用测距算法时定位误差小。为了提高室内LED半功率角的辐射范围, 并消除其辐射“盲区”, 提出了一种基于LED半功率角的IRT-N三角阵列, 该阵列通过利用地面上的LED半功率角圆形辐射范围相切, 将LED组合排列成等腰直角三角形。相较于传统斯派罗法则构建的方形阵列, IRT-N三角阵列将地面接收信号强度和接收功率高于平均值的辐射面积分别提高了25.75%和16.45%。该阵列构建复杂度低、半功率角辐射范围广, 更适宜在VLC室内定位领域中推广应用。

Abstract

In the field of VLC indoor positioning, the signal intensity is grate in the range of the LED semi angle half power (SAHP), and the positioning error is smaller when using the ranging algorithm within the radiation scope. It proposes an IRT-N triangle array based on LED SAHP to expand the radiation scope and eliminate the SAHP fade area. The IRT-N triangle array arranges the LED combinations into an isosceles right-angled triangle through the tangent LED SAHP circular radiation scope on the ground. The IRT-N triangle array increases the radiation area above average of the ground received signal strength and received power by 25.75% and 16.45% respectively, compared to the traditional square array that is structured by the Sparrows law. It has the advantages of low complexity and wide range of LED SAHP radiation. In addition, it is more suitable for popularization and application in the field of VLC indoor positioning.
