Optical wireless communication method and apparatus

摘要

An optical wireless communication method and apparatus configured to distinguish optical LAN data from optical noise is disclosed. The apparatus communicates using Manchester coded data via a connector connected to a personal computer. The Manchester coded data from the computer are converted to NRZ transmission data to be temporarily stored and read out. A frame of the read out data is appended with a head leader, and end data, at the head and end of the frame respectively to be convened to the DMI transmission optical data. The optical data inserted between the head leader and END data are receivable and can be distinguished from optical noise. The DMI received data removed from the head leader and end data are convened to data of the Manchester code in contrast with the transmission side to be delivered as the Manchester data via the connector. As the optical data with the head leader and end data are distinguishable from optical noise, high sensitive optical receivers are available.
