Abstract
A system includes first signal processing circuitry to transmit a signal including a plurality of data streams over a link. The first signal processing circuitry generates a plurality of composite data streams by overlaying at least one first data signal of the plurality of data signals in a first data layer with at least one second data signal of the plurality of data signals in a second data layer. Second circuitry processes the plurality of composite data streams to associate with each of the plurality of composite data streams a function to provide minimization of a time-bandwidth product of the plurality of composite data streams to enable transmission of each of the plurality of composite data streams on the link at a same time.
