Abstract
Systems and techniques for physical layer encryption (PLE) using beamforming. The techniques are based on the principles of Linear Amplification with Nonlinear Components (LINC) to produce a transmit signal with limited dynamic range. A masking signal is structured based upon a source data signal to produce a transmit signal with limited dynamic range, while providing a high degree of secrecy.
