Abstract
A method of nonlinear and affine signal processing includes the steps of introducing an input signal into a system which exhibits nonlinear behavior, the input signal including a target signal and a secondary signal. By virtue of its nonlinear design, the system generates nonlinear artifacts of the target signal and the secondary signal. These nonlinear artifacts are in turn used as a novel form of signal diversity. In one embodiment, the identification of the nonlinear artifacts is used to resolve defects that have been created as a result of sub-Nyquist sampling. In another embodiment, the identification of the nonlinear artifacts is used to locate and strengthen the power of a target signal that falls beneath the noise threshold for the system.
