Correlative level coding for binary-data transmission

Abstract

A new approach to binary-data transmission, termed correlative level coding, is presented, along with practical aspects based on research conducted during the past few years. Following a review of basic data-transmission concepts and definitions, the author discusses the general form of the level-coded correlative techniques, as well as the specific codes with and without carrier modulation. In the error-detection process, it has been found that with this type of system it is unnecessary to introduce redundant digits into the original data stream.
