Abstract: 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.
