Amplitude Division Multiple Access Using Uniqueness of Prime Factorization

Abstract

A new method of amplitude division multiplexing (ADMA) is proposed, where a single channel can be used to transmit multiple digital signals simultaneously using the concept of prime number factorization. This method contrasts with the currently used methods such as frequency-division multiple access (FDMA), in which the total bandwidth available in a channel is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal. Comparison of the proposed method with a popular PAM technique-2B1Q method is made. Distinct advantages of the proposed method and a few applications are presented.
