Abstract
Improved apparatus and methods for utilizing holographic waveforms for a variety of purposes including communication. In one exemplary embodiment, the holographic waveforms are wideband in nature and transmitted over an RF bearer medium to provide, inter alia, highly covert and robust communications. The wideband signal is generated without resort to a carrier (and any associated upconversion in the transmitter or downconversion in the receiver). In one embodiment, the radiated signals are of sufficiently low power such that the transmitter does not require a power amplifier.
