Paper Abstract

An indoor wireless communication system using commercial white LED is presented in this paper. OOK (On-Off Keying) modulation is adopted in the transmitter module. Data transmission is realized based on RS-485 protocol. A DC-balanced coding with error check and correction abilities is applied to avoid blinks and improve the performance of the system. The system can keep 10-7 error bit rate within 2.5m reach at a rate up to 115200 bps.
