Abstract
A processing device is provided. The processing device comprises one or more interfaces configured to transmit information to a nonlinear device and processing circuitry configured to control the one or more interfaces and to. Further, the processing circuitry is configured to transmit an excitation signal to the nonlinear device and to receive response information from the nonlinear device. Further, the processing circuitry is configured to determine a linear response of the nonlinear device based on the response information and to determine a nonlinear response of the nonlinear device based on the determined linear response.
