Abstract
Various embodiments relate to a method and apparatus for a method for under sampling a RF carrier signal, the method including receiving, by an analog digital converter, the RF carrier signal, selecting, by a multiplexer, a clock signal which includes a first clock signal and a second clock signal which are phase shifted, receiving, by the ADC, the clock signal which has a frequency less that the frequency of the RF carrier signal, sampling, by the ADC, the RF carrier signal using the selected clock signal and demodulating, by a digital signal processor, the RF carrier signal into I channel data and Q channel data for I/Q demodulation.
