摘要 |
The invention is related to a device comprising: generating unit configured to generate a feedback signal; setting unit configured to set a predetermined frequency shift to the feedback signal; evaluating unit configured to evaluate distortion caused in a transmission chain on the basis of the frequency shifted feedback signal; adapting unit configured to adapt quadrature modulation pre-distortion algorithms of the transmission chain; wherein the setting unit is further configured to set the frequency of the feedback signal to an original frequency value; wherein the evaluating unit is further configured to evaluate distortion caused in the feedback chain based on the feedback signal having the original frequency; wherein the adapting unit is further configured to adapt quadrature demodulation pre-distortion algorithms of the feedback chain; and wherein the adapting unit is further configured to adapt other pre-distortion algorithms.
