Modulation of orthogonal carriers by asynchronous digital signals
Abstract
This article describes a modem for the transmission of two asynchronous signals on one radio channel. The aim is to reduce the cost of terminal equipment for short distance links. The proposed modulation system uses the orthogonality of two carriers and avoids the use of a multiplexer-demultiplexer.
