Abstract
Interference cancellation is provided, according to certain aspects, by a filter, a signal detection circuit, synthesis circuitry and signal-generation circuitry. The filter is used to filter an incoming signal having an associated signal-to-noise metric and to output therefrom a filtered signal having an interference attribute of the incoming signal by amplification and/or isolation. The signal detection circuit is used to detect the interference attribute in the filtered signal. The synthesis circuitry is used to synthesize interference in the incoming signal based on the interference attribute. The signal-generation circuitry is used to generate, in response to the synthesized interference in the incoming signal, a filtered version of the incoming signal which provides an improved signal-to-noise metric.
