Abstract
A method of generating inphase and quadrature signals from a polar receiver providing a phase derivative signal and an envelope magnitude signal comprising receiving an estimated phase derivative signal; generating an estimated phase signal; mapping the estimated phase signal to an angular value; converting the estimated phase signal to an inphase signal and a quadrature signal based on the angular value; and, providing the inphase signal and quadrature signal to a demodulation circuit.
