Abstract
An infrared communication system for transmitting a digital bit stream by telemetry in the presence of background radiation wherein each bit in the data stream is represented by a signature set of pulses designating either a binary one or a binary zero. A receiver detecting an infrared signal filters the signal to detect the signature sets of pulses generated by the transmitter. The pulses are transmitted according to a specific communications protocol.
