Research of modulation technology of visible light communication in coal mining face based on white LED

  • The paper introduced general structure of visible light communication system in coal mining face and had a study on key technologies of visible light communication in the coal mining face, including carrier modulation technology, design of modulation driving circuit and modulation bandwidth, and concludes that white LED considers both bandwidth and luminous efficiency is ideal light source in the visible light communication system.
