This work proposes using the changes in the LEDs’ spectral emission induced by temperature variations to implement emitters for new communication channels in Optical Camera Communication (OCC) systems. If a camera can discriminate the shift in LEDs’ spectral response, these modifications can be contemplated as a new data channel. The main advantage is that new channels can be obtained from the same physical optical emitter device, only temperature changes are needed. Thus, in this work, the use of multispectral or hyperspectral cameras as OCC receivers is proposed to increase the number of available communication channels, taking advantage of the high spectral resolutions of the camera devices.

使用LED光谱发射变化的光学多光谱相机通信

这项工作提出利用温度变化引起的LED光谱发射的变化来实现光学相机通信(OCC)系统中新通信通道的发射器。如果摄像机可以区分LED光谱响应的变化,则可以将这些修改视为新的数据通道。主要优点是可以从同一物理光发射器设备获得新的通道,只需要改变温度即可。因此,在这项工作中,提出利用多光谱或高光谱相机作为OCC接收器,以利用相机设备的高光谱分辨率来增加可用通信通道的数量。
