Patent ID: 8064560

Claim:
A system for detecting a signal across multiple Nyquist bands, the system comprising: an analog to digital converter (ADC) configured to sample an input signal; a clock signal generator in signal communication with the ADC, the clock signal generator configured to selectively output a sample clock signal to the ADC, the sample clock signal having a sample frequency selected from a plurality of distinct sample frequencies; and a processor in signal communication with an output of the ADC and an input of the clock signal generator, the processor configured to: a) extract information from a predetermined desired signal within the sampled input signal; b) determine whether a possible signal that interferes with the desired signal exists at a next sampling rate selected from a plurality of sampling rates using a currently selected sampling rate; c) instruct the clock signal generator to generate the next sampling rate if the processor determines that the possible interfering signal does not exist; d) if the processor determines that the possible interfering signal does exist, determine whether the possible interfering signal exists at each of the other sampling rates selected from the plurality of sampling rates using the currently selected sampling rate until a sampling rate is found that does not have the possible interfering signal; and e) instruct the clock signal generator to generate the sampling rate that was determined to not have the possible interfering signal, if the processor determines that the sampling rate exists, wherein the processor is configured to repeat steps a) through e).
