Abstract
Systems and methods for characterizing an undersampled receiver are disclosed. In one embodiment, one or more probe signals are provided to an input of an undersampled receiver. Each of the one or more probe signals has selective frequency components that ensure that aliases in a corresponding output signal of the undersampled receiver are unique. The undersampled receiver is then characterized based on the output signal(s) of the undersampled receiver. The selective frequency components of the one or more probe signals enable un-aliasing of the one or more output signals of the undersampled receiver and, as such, the undersampled receiver can be characterized.
Claims22
A method of characterizing an undersampled receiver, comprising:
- providing one or more probe signals to an input of the undersampled receiver;
- and
- characterizing the undersampled receiver based on one or more output signals of the undersampled receiver in response to the one or more probe signals;
- wherein each probe signal of the one or more probe signals has selective frequency components that ensure that aliases in a corresponding one of the one or more output signals of the undersampled receiver are unique.
A system comprising:
- an undersampled receiver;
- a means for generating one or more probe signals and providing the one or more probe signals to an input of the undersampled receiver;
- and
- a means for characterizing the undersampled receiver based on one or more output signals of the undersampled receiver in response to the one or more probe signals;
- wherein each probe signal of the one or more probe signals has selective frequency components that ensure that aliases in a corresponding one of the one or more output signals of the undersampled receiver are unique.
