This invention describes a compressive method of transmitting digital information. Parallel communications branches (103, 103(a),...103(n)) are coded to transmit ensembles of bits coded so that they can be added (203) together and forwarded over a single transmitted channel without interference. Decoding occurs at a receiving station (6). In accordance with the invention an iterative method of modulating multiple simultaneous signals is accomplished, so that multiple closely spaced signals can pass through a narrow bandpass filter (106), where the bandwidth of the communications highway connecting a transmit and receive station is determined by the communication bit rate of the simultaneous bit ensemble. The invention is also advantageously applicable to a compressive digital storage system.

Procédé de transmission d'informations numériques par compression. Des branches (123, 103(a),...103(n)) de communication parallèles sont codées pour transmettre des ensembles de bits codés de sorte que ces derniers peuvent être ajoutés (203) les uns aux autres et transmis sur une seule voie de transmission sans interférence. Le décodage s'effectue à la station de réception (6). Conformément à la présente invention, un procédé itératif de modulation de signaux simultanés multiples est appliqué, de sorte que des signaux multiples étroitement espacés peuvent passer à travers un filtre (106) à bande étroite dans lequel la largeur de bande de l'autoroute de communication connectant des stations d'émission et de réception est déterminée par le débit binaire de communication de l'ensemble de bits simultanés. La présente invention peut également être appliquée avantageusement à un système de mise en mémoire numérique par compression.
