ELEKTRONISCHE VORRICHTUNG IM ZUSAMMENHANG MIT EINEM PHOTOVOLTAISCHEN MODUL ZUR OPTIMIERUNG DES DURCHSATZES EINER BIDIREKTIONALEN VLC-ÜBERTRAGUNG

摘要

The invention relates to a bidirectional wireless communication device which is based on the use of light, including emitting modules, each emitting amplitude- and/or phase-modulated light; and a receiving module made up of: a photodetector illuminated by said modulated light and generating a modulated electrical signal in response to said modulated light; and a processing module for processing the signal generated by said photodetector. The receiving module includes an electronic means positioned between the photodetector and the signal-processing module and capable of matching the impedance of the photodetector to maximize the signal-to-noise ratio of the electrical signal by minimizing distortions of said electronic signal associated with incorrect impedance matching at the output of the photodetector, while maximizing the level of the modulated electrical signal and the throughput of transmitted data.
