Description

technical field

[0001] The present invention relates to the technical field of visible light communication, in particular to a communication system combining power line communication and visible light communication with an electric signal regeneration link and a method for optimizing a visible light access cell architecture based on the communication system. Background technique

[0002] In order to solve how to transmit data conveniently and at low cost to "new LED lights that use visible light for data transmission and reception", the combination of power line communication and visible light communication has become a cutting-edge research direction. However, in the existing solutions, one type of method is to use a coupler to extract the electrical signal transmitted in the power line and send it to the LED, and then the LED drive unit converts the voltage signal into a current signal, and then modulates the light intensity of the LED ( Such as the Chinese patent applicat...
