ABSTRACT:
This invention describes a compressive method of transmitting digital information. Parallel communication branches are coded to transmit ensembles of bits coded so that they can be added together and forwarded over a single transmitted channel without interference. Decoding occurs at a receiving station. 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, 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.
