摘要
针对室内可见光通信中光学天线存在的视场小、接收面光能分布不均匀,以及低功率光源条件下接收功率低的问题,设计了作为可见光通信系统光学天线的平板型聚光器,推导出适用于平板型聚光系统的光学增益理论公式。在一个(5×5×3) m房间中对平板型聚光器作为光学天线的接收功率分布进行仿真,得到直射和非直射链路信道下视场角为50°的平板型聚光器接收房间内各位置的光功率比直接探测时分别提升了16.2411 dBm和16.4956 dBm。
Abstract
Optical antenna for indoor visible light communication has such problems as small field of view, non-uniformity of the irradiance distribution at the receiver, and low received power under the low power light source condition. We design a planar concentrator as an optical antenna and establish a gain theory. We establish a visible light communication system model based on planar concentrators in a 5 m×5 m×3 m room, which use a planar concentrator with a field of view of 50° as an optical antenna. The simulation results show that the received average powers after using the concentrator in the direct link channel and the non-direct link channel are increased by 16.2411 dBm and 16.4956 dBm compared with that under the direct detection.
