Abstract
Systems and methods for demodulating a signal is described. A device can receive a modulated signal that encodes data. The device can sample a voltage of the modulated signal to generate a plurality of samples in digital domain. The device can determine in-phase data and quadrature data of the plurality of samples. The device can determine amplitude data and phase data based on the in-phase data and the quadrature data. The device can decode the amplitude data and phase data into digital symbols that represent the data encoded in the modulated signal.
