Abstract
Systems and methods for detecting a signal across multiple Nyquist bands. The systems include an analog to digital converter (ADC), a clock signal generator configured to output a sample clock signal to the ADC, and a processor configured to process sampled signals and control the clock signal generator. The processor is configured to iteratively identify a desired signal, determine whether a possible interfering signal exists at a next sampling rate, and instruct the clock signal generator to generate the next sampling rate if the processor determines that a possible interfering signal does not exist. The methods include sampling an input signal at a first sampling rate, processing the sampled signal to extract information from a desired signal, determining whether a possible interfering signal exists at a next sampling rate, and sampling at the next sampling rate if it is determined that a possible interfering signal does not exist.
