Correlation-recovered adaptive majority multiplexing
John A. Gordon, Robert P. Barrett · Proceedings of the Institution of Electrical Engineers · 1971
A novel method of multiplexing based on a pattern-recognition technique is described, in which binary data are combined for transmission over a common medium by modulation onto binary codewords. A majority-logic gate forms the transmitted (binary) signal from the modulated codewords. Demodulation is effected by a correlation process using digital matched filters. The system exhibits an adaptive property in the relationship between the channel error-correcting properties and the number of channels in use. Theoretical and experimental results are reproduced, and a description of a prototype equipment is included.
