1. A method for signal predistortion comprising:

  • receiving a plurality of input driving signals for driving an antenna array;

    converting the plurality of input driving signals to a plurality of input directional signals having fewer signals than the plurality of input driving signals, each of the plurality of input directional signals being associated with a respective direction of a plurality of directions of emission from the antenna array, wherein the plurality of directions of emission comprises a direction of a side lobe of an antenna pattern associated with the plurality of input driving signals;

    processing the plurality of input directional signals to form a plurality of directional predistortion signals each of the plurality of directional predistortion signals being associated with a respective one of the plurality of input directional signals;

    using the plurality of directional predistortion signals to predistort the plurality of input driving signals to yield a plurality of predistorted driving signals; and

    providing the plurality of predistorted driving signals for driving the antenna array.
