摘要： A distortion estimation apparatus for estimating distortion includes a feedback element, a nonlinearity determiner, and a distortion simulator. The feedback element provides a feedback signal derived from a distorted output signal of the distorting element. A signal processing quality of the feedback element is lower than an associated signal property of the distorted output signal. The nonlinearity determiner receives the feedback signal and an input signal to the distorting element or a signal derived from the input signal. The nonlinearity determiner determines an estimated transmission characteristic of the distorting element by relating signal properties of the feedback signal and the input signal or the signal derived from the input signal. The distortion simulator estimates the distortion caused by the distorting element based on the input signal or the signal derived from the input signal and the estimated transmission characteristic.
