1. A method comprising:

  • detecting a presence of an interference signal on a channel of a Vehicle-to-Everything (V2X) radio which obscures payload data that is included in a V2X message received via the channel;

    determining that a source of the interference signal present on the channel is both on-board the V2X radio and off-board the V2X radio and that a type of the interference signal is combination interference;

    canceling out the interference signal from the V2X message to generate a modified version of the V2X message including the payload data which is substantially unobscured by the interference signal by;

    applying a self-interference cancellation technique to cancel out any self-interference from the V2X message;

    applying an adjacent-channel interference cancellation technique to cancel out any adjacent channel interference from the V2X message; and

    determining an execution order to cancel out the self-interference and the adjacent channel interference from the V2X message based on one or more order determination factors; and

    providing the modified version of the V2X message to a vehicle component so that the vehicle component provides its functionality based on the payload data and not the interference signal.
