Abstract:
A system can include a signal image correlator receives a discrete frequency domain representation of a signal tone in an interleaved analog-to-digital (IADC) signal and an image of the signal tone in the discrete frequency domain representation of the IADC signal and determines a correlation between the signal tone and the image of the signal tone, a power of the signal tone and a power of the image of the signal tone. The system can also include a frequency domain estimator that determines an instantaneous frequency domain mismatch profile estimate based on the correlation between the signal tone and the image of the signal tone. The system can further include an averaging filter that averages the instantaneous frequency domain mismatch profile estimate over time to provide a frequency domain mismatch profile estimate.
