Abstract

Improved apparatus and methods for utilizing holographic waveforms for a variety of purposes including communication. In one exemplary embodiment, the holographic waveforms are transmitted over an RF bearer medium to provide, inter alia, highly covert and robust communications. The baseband processor(s) are configured to selectively scale their architecture for performing the mathematical transforms (e.g., Fourier) or other operations (such as high speed phase-coding) in order to meet one or more operational requirements, such as reduced power consumption, changes in data rate, etc.
