Abstract:
An RF reception system and method uses IF quadrature mixing, in which there is further mixing and channel filtering in the digital domain, to isolate a frequency of interest. A coefficient estimator is used for generating a phase correction coefficient and an amplitude correction coefficient from filtered in-phase and quadrature desired signals and from filtered in-phase and quadrature image signals.
