THE METHOD OF MULTIPLE CHANNEL INTELLIGENCE COMMUNICATION WHICH COMPRISES GENERATING A PLURALITY OF WAVERFORMS BEARING A MUTUALLY ORTHOGONAL POLYNOMIAL RELATION TO EACH OTHER, AMPLITUDE MODULATING SAID WAVE FORMS WITH A PLURALITY OF INTELLIGENCE SIGNALS, COMBINING SAID MODULATED WAVEFORMS FOR TRANSMISSION, RECEIVING SAID COMBINED MODULATED WAVEFORMS, DERIVING A SYNCHRONIZING SIGNAL THEREFORM, CORRELATING THE COMPOSITE SIGNAL WITH THE ORTHOGONAL POLYNOMIAL WAVEFORM FOR EACH CHANNEL, SAMPLING THE CORRELATION WAVEFORM IN EACH CHENNEL, AND SMOOTHING THE SAMPLED CORRELATION WAVEFORM IN EACH CHANNEL FOR DERIVATION OF THE ORIGINAL INTELLIGENCE SIGNALS FOR UTILIZATION.
