ABSTRACT:
An optical wireless transmission system providing short-distance communication, such as for linking a personal computer to a LAN, utilizes direct baseband modulation of optical signals, but provides simultaneous bidirectional transmission of data between a pair of optical transmitting/receiving units while also enabling a data clock signal to be easily regenerated from a received optical signal. Effects of signal noise due to artificial illumination are eliminated by a suitable choice of transmission bandwidth, and bandpass filtering of a received data signal.
