    Abstract: The pre-distorter controller determines at (210) if the residual distortion in the amplifier output is above a threshold. If so, the phase and amplitude of a pre-distortion signal combined with the amplifier input signal are adjusted sequentially to reduce the residual distortion below the threshold. When the residual distortion falls below the threshold, step (214) determines if the residual distortion is below a second, smaller, threshold. If not, step (218) makes small adjustments to the phase and amplitude of the pre-distortion signal sequentially and the residual distortion is again tested at (214) to determine if it is now below the second threshold. If it is, then further adjustments are not made unless the residual distortion level moves above the second threshold. The control process can also be used with a feed forward lineariser to minimise output distortion (FIG. 5) or unwanted input signal components in the signal led forward (FIG. 6).
