BACKGROUND NOISE-IMMUNE LED-BASED COMMUNICATION DEVICE

摘要

A background noise-immune LED-based communication device comprises at least one LED signal transmitter emitting a Manchester code signal generated by a Manchester coding technology; and at least one optical receiver receiving the Manchester code signal from the LED signal transmitter. The present invention applies the Manchester coding technology to visible-light communication devices, enabling the LED-based communication device to transmit the Manchester code signal, whereby is decreased noise and promoted signal quality.
