Abstract
A method and system for detecting and characterizing an input signal receive a signal having an in-phase (I) component and a quadrature-phase (Q) component. A first IQ sample of the signal is acquired at a first point in time, and a second IQ sample of the signal is acquired at a second point in time, Using one or more processors, a delayed complex conjugate multiply (DCM) is applied to the first IQ sample of the signal and the second IQ sample of the signal to produce a constant product having an in-phase (IC) component and a quadrature-phase (QC) component. A signal magnitude and a signal frequency are determined from the IC component of the constant and the QC component of the constant, using the one or more processors.
