Abstract
An optical code division multiple access transmission and reception system is presented. The transmission system comprises an optical comb generator for producing multiple discrete optical signal components comprising a plurality of equally spaced wavelength components. A serial-to-parallel converter is connected with the optical comb generator for receiving receiving the serial signal components and for converting a selected group of the serial signal components into parallel signal components. An optical free-space code mask is connected with the serial-to-parallel converter for receiving the parallel signal components and for selecting two separate groups of optical signal components to generate two subsets of signal components, each for representing an associated binary data value from a data stream. The transmission system may comprise further components to enable transmission via fiber optic cable or into free-space via an antenna. The reception system operates opposite the transmission system to de-code a coded signal, obtaining the original data.
