Method and System for Implementing Visible-Light Communication, Sending Apparatus, and Receiving Apparatus
First Claim
1. A method for implementing visible light communication, comprising:
- after performing constellation modulation on data to be sent, a sending end mapping a modulated signal to a corresponding luminescent light source; and
transmitting the data to be sent to a receiving end through an optical signal, and the receiving end converting the received optical signal into an electrical signal; and
the receiving end determining a constellation modulation signal according to a luminescent light source corresponding to the received signal, and demodulating the constellation modulation signal to obtain received data.
