Receptor para Sistemas de Comunicação por Luz Visível Baseados na Modulação OOK-M-FSK

This work presents an analysis of the design and operation of a receiver for visible light communication systems based on the OOK-M-FSK modulation. The functional blocks of the circuit are presented, as well as the demodulation algorithm for the studied VLC signal. Experimental results shown the proper operation of the circuit and the algorithm, since the VLC OOK-M-FSK signal were correctly demodulated for several tests and studied conditions.
