摘要： Described herein are methods and apparatuses for receiving a desired signal at a signal receiver with an undersampling frequency. A signal converter with a local oscillator frequency, a bandpass filter, and an analog-to-digital converter are used to generate an aliased discrete-time spectrum from an input analog spectrum. In order to determine the presence of interfering signals in the aliased discrete-time spectrum and, if present, separate a desired signal from the interfering signal, the local oscillator frequency is shifted. The original discrete-time spectrum and the resulting shifted discrete-time spectrum are both analyzed to select a local oscillator frequency that does not cause interference with the desired signal when the discrete-time spectrum is generated. The selected local oscillator frequency is then utilized to process the desired signal.

摘要： 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.

摘要： A system and method for determining a received signal frequency by sampling the received signal at a rate less than twice a predefined nyquist rate. The system includes a distorting component configured to distort the received signal in a frequency dependent manner, at least one analog to digital converter configured to sample the received signal and the distorted signal at a rate less than twice a predefined nyquist rate, and a processing component configured to determine a frequency of the received signal based on the sampled received signal and the sampled distorted signal. The method includes distorting the received signal, sampling the received signal and the distorted signal at a rate less than twice a predefined nyquist rate, and determining a frequency of the received signal. In an embodiment, distorting includes at least one of distorting an amplitude or a group delay of the received signal.
