Abstract
In some embodiments, a signal transmitter includes a processor that converts information to be emitted into a plurality of signals, each signal having an emitting waveform, wherein at least two of the time-frequency distributions of emitting signal waveforms are separated from one another in the joint time-frequency plane by a parallelogram shaped regions. In some embodiments, a signal receiver includes a processor that separates received time-frequency spread waveforms from one another, the time-frequency spread waveforms are parallelogram-shaped in the joint time-frequency plane.
