Abstract: A communication system for transmitting a plurality of analog or digital information signals to a receiver with an improvement in band width utilization over conventional systems. A system with a plurality of swept frequency encoding signals, each frequency modulated at the same rate but with different phase, and in the preferred embodiment, means for amplitude modulating each encoding signal with a double sideband, suppressed carrier signal which may comprise two information signals, with the modulator outputs summed to provide a combined signal for further processing incorporating additional information signals and/or for transmission to a receiver. A system utilizing three such modulation arrangements for eighteen information signals and three combined signals, with the three combined signals used for amplitude modulating another set of three swept frequency encoding signals to provide a further combined signal for transmission to a receiver. A receiver with a decoding system providing the reverse of the encoding system. A receiver wherein one or more of the transmitted information signals can be selected for reproduction.
