Abstract

A method of encoding and decoding a binary modulated light spectrum to recover encoded intelligence. The method enables reliable and accurate decoding of wave division multiplexed data. The method incorporates a step of encoding data and a step of decoding the data which employs a photo-detector array. This method of encoding and decoding data compensates for variations in signal level, spectral position and spectral width with no degradation in reconstructed data.
