Abstract
A method for transforming and reconstructing a signal includes receiving a plurality of samples of a waveform of the signal at different points in time. The waveform of the signal is transformed, for each sample, into an in-phase (I) component and a quadrature (Q) component. A derotational circuit applies a delayed complex conjugate multiple (DCM) to the signal to determine a constant product having an I component (Ic) and a Q component (Qc). A magnitude component is determined based on Ic and Qc. A delta phase component is determined based on Ic and Qc. The magnitude component is processed to create a processed magnitude component. The delta phase component is processed to create a processed delta phase component. An IQ waveform is created by reconstructing the waveform of the signal based on the processed magnitude component and the processed phase component.
