异构可见光及RF混合链路软切换表现分析

现有的可见光及射频(RF)混合链路仍然局限于空间辐射特性单一的朗伯光波束配置, 面向商用发光二极管的非朗伯空间辐射特性, 提出一种基于典型LUXEON Rebel非朗伯光波束的可见光及RF混合链路软切换方案, 并进行了仿真分析。仿真结果表明: 设定RF接入点在近端(dr=10 m)和远端(dr=60 m)时, 所提出的异构非朗伯光波束配置混合链路吞吐量的最大值分别为370.72 Mb/s、275.68 Mb/s；发射功率为2~15 W时, 比传统朗伯光波束配置混合链路可引入高达约14 Mb/s的吞吐量增益。

Abstract

The current visible light and radio frequency(RF) hybrid links are still obviously limited to the Lambertian beam configuration with simple spatial radiation characteristics. For addressing this issue, based on the non-Lambertian space radiation characteristics of commercial LED, a soft switching scheme of hybrid link between visible light and RF based on typical LUXEON Rebel non-Lambertian beam is proposed, and simulation analysis is carried out. The simulation results show that when the RF access point is set at the proximal end(dr=10 m) and the distal end(dr=60 m), the maximum throughput of the hybrid link of the proposed heterogeneous non-Lambertian beam configuration is 370.72 Mb/s and 275.68 Mb/s, respectively. When the transmission power is from 2~15 W, the hybrid link can introduce a throughput gain of up to about 14 Mb/s compared with the traditional Lambertian beam configuration.
