Abstract:
1. A communication device for estimating a distortion caused by a distorting element, the communication device comprising: a feedback element configured to provide a feedback signal derived from a distorted output signal of the distorting element, wherein a signal processing quality of the feedback element is lower than an associated signal property of the distorted output signal; a memory configured to store executable instructions; and a processor, coupled to the memory, configured to execute the executable instructions to at least: receive the feedback signal and an input signal to the distorting element or a signal derived from the input signal; determine 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, and estimate 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.
