Abstract
Generating apparatus providing a preferred pulse envelope which is compared to the envelope of output pulses from a nonlinear power amplifier, the error between the two being used, along with a stored predistorted pulse, to generate an updated predistorted pulse that is utilized to modulate the input signal to the nonlinear amplifier to produce a pulse at the output thereof having the preferred envelope and to update the stored predistorted pulse.
