Abstract

This paper presents a novel visible light communication receiver architecture, designed for automotive applications. A crucial problematic in this area is the design of a suitable receiver able to face the problems caused by the dynamic situations, by the long distances and also by the environmental conditions. In such circumstances, a solution would be to adapt the communication's data rate to channel conditions, meaning that the communication would take place using different data rates, depending on the signal-to-noise ratio (SNR) and the message priority. Considering the digital filtering a better performance, the proposed architecture considers the usage of digital signal processing as an alternative to the analog signal treatment. The visible light communication receiver proposed in this paper addresses the above-mentioned issues and enables a robust communication even at low SNR.
