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.

Abstract: Provided herein are methods and devices for facilitating cellular handover in high Doppler environments. The method comprises receiving an input from one or more antennas, the input comprising a first component received over a first communication path from a serving base station and a second component received over a second communication path that is different to the first communication path. The method further comprises performing signal compensation on the first component over a communication branch, measuring one or more indications of strength, quality or frequency of the first component and communicating wirelessly with the serving base station over the communication branch; and in parallel to the communication branch, performing signal compensation on the second component over a measurement branch and measuring one or more indications of strength, quality or frequency of the second component in order to assist a decision regarding handover of communication to the second communication path.
