A computer-implemented method for the self-calibration of an inertial sensor. The method includes: establishing data that relate to the inertial sensor; subdividing the data into training data and test data; setting a first target accuracy value for a first artificial neural network that includes linear activation functions; training the first artificial neural network using the training data; inputting the test data into the trained first artificial neural network in order to obtain a first output value of the first artificial neural network; establishing a first output accuracy value based on a comparison result between the first output value and the test data; storing weightings and the linear activation functions of the first artificial neural network in a memory unit of the inertial sensor if the first output accuracy value is greater than the first target accuracy value, or otherwise, training the first artificial neural network again using the training data.

A computer-implemented method for inferring a device feature of a device produced on a wafer. The method includes: providing a wafer feature model associating a wafer position indicating a position of a produced device on the wafer to a device feature, wherein the wafer feature model is configured to be trained by one or more wafer feature maps and particularly configured as a Gaussian process model, providing a sample device feature of at least one device at a sample wafer position, and inferring the device feature of at least one other device of the wafer depending on the provided wafer feature model.

A signal processing device is usable in a communication system and includes a signal path, a signal detector, a signal synthesizer, a transmission unit, and a receive path including an analog-to-digital converter. The signal path transmits a transmission signal that was transmitted by the communication system and that contains a communication signal. The signal detector detects, and generates an activation signal in response to, an interference signal contained in the transmission signal and occurring due to narrowband interferences. The signal synthesizer generates an approximation signal for the interference signal upon the presence of the activation signal. The transmission unit receives the transmission signal transmitted by the signal path and the approximation signal, and outputs a difference signal between the transmission signal and the approximation signal. The analog-to-digital converter converts a signal generated based on the difference signal into a digital signal.
