US 10,812,119 B1 : Systems and methods involving interference cancellation

Systems and methods involving interference cancellation, 2020

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 amplifi cation 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 .
