Abstract: Various embodiments relate to a method and apparatus for over sampling a RF carrier signal, the method including receiving, by an ADC, the RF carrier signal, sampling, by the ADC, the RF carrier signal using the selected clock signal which is at least quadruple the RF carrier signal, down sampling, by a RF-DSP, the RF carrier signal by a factor of two to generate I channel data and Q channel data, mixing down, by the RF-DSP, the I channel data and the Q channel data, and outputting, by the RF-DSP, the I channel data and Q channel data to a baseband DSP.

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.
