Holographic communications using multiple code stages

摘要

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. A multi-stage (e.g., dual) phase-coding approach is used in conjunction with a mathematical transform to further enhance robustness and security of the radiated waveforms.
