  • Cancellation of interference and harmonics
    Patent number: 11152967
    Abstract: There is provided systems and methods for mitigating interference from an interference signal. In one implementation the system comprises cancellation circuitry configured to: receive a first signal from a first antenna, the first signal comprising an interference component deriving from the interference signal and a desired component deriving from a desired signal; and receive a second signal comprising an interference component deriving from the interference signal and received at one or more of a different antenna or a different frequency to the first signal. The interference component in the second signal is stronger than that the interference component in the first signal. The cancellation circuitry is further configured to derive a cancellation signal from the second signal; generate an output signal by subtracting the cancellation signal from the input signal to substantially remove the interference component from the first signal; and output the output signal.
