ABSTRACT:
A radio receiver measures a signal quality metric and modifies attributes of a local oscillator signal in response thereto. A digital signal processor may be used to determine a signal-to-noise-plus-distortion ratio (SNDR) of a baseband signal, and the overlap of two quadrature-related local oscillator signals may be modified.
