20 Claims

1. A system for transmitting digital data, comprising: a digital receiving mechanism to receive an incoming stream of digital information on at least one incoming digital line, the digital information being in a binary format; a weighing mechanism to generate respective weighing factors using the digital information; a signal generation mechanism equipped to generate a plurality of smooth Time-and-Frequency-Bounded functions; a mapping mechanism, coupled to the signal generation mechanism, to apply weighing factors generated by the weighing mechanism to a corresponding Time-and-Frequency-Bounded function, and subsequently summing the weighted Time-and-Frequency-Bounded functions to thereby generate a corresponding plurality of Time-and-Frequency-Bounded packets, the plurality of Time-and-Frequency-Bounded packets comprising a Time-and-Frequency-Bounded information stream; and a transmission mechanism to transmit the plurality of Time-and-Frequency-Bounded packets over the transmission medium.
