在本文中,我们考虑了服务于密集物联网部署的多数据流VLC网络,并提出了一种“圆顶灯泡”,该灯泡由带有圆顶透镜结构的多LED阵列组成,以分离每个LED的光束以进行空间重用。每个LED都具有兰伯氏辐照度分布,可以使用宽视场(FOV)镜头系统收集并定向到接收器位置。在视场内,每个LED的发散角度被缩小,以提高空间的再利用,这也带来了点状照明的问题。我们从照度均匀性和提供给室内接收器的信噪比(SINR)两方面分析了圆顶灯泡。我们还提出了一个基于模拟信噪比的信道模型。
In this paper, we consider multi-datastream VLC networks serving dense IoT deployments and propose a "dome bulb" that consists of a multi-LED array with a dome-shaped lens structure to separate each LED's beam for spatial reuse. Each LED has Lambertian irradiance distribution that can be collected and directed to receiver location using a wide field-of-view (FOV) lens system. Within the FOV, each LED's divergence angle is narrowed to improve spatial reuse, which also brings the problem of spotty lighting. We analyze the dome bulb in terms of illumination uniformity and Signal-to-Interference-Noise Ratio (SINR) provided to receivers in the room. We also present a channel model based on the simulated SINR.
