Claim 0:
1. A device for generating training data sets for signal type recognition, comprising: at least one radio frequency signal generator for generating at least one artificial radio frequency signal; a radio frequency receiver connected to the at least one radio frequency signal generator for receiving the at least one artificial radio frequency signal generated by the at least one radio frequency signal generator; and a signal data recorder connected to the radio frequency receiver for storing the radio frequency signal received by the radio frequency receiver as a training data set configured for training a machine learning module to recognize a predefined signal type; wherein the at least one radio frequency signal generator includes at least two radio frequency signal generators, the at least two radio frequency signal generators being configured to generate artificial radio frequency signals that emulate the radio frequency behaviors of at least two of: an IoT-device, a cellular device, a non-cellular device, a broadcasting device, a radio device, a satellite, a navigation device or a radar, wherein the device further comprises a power combiner, wherein each of the at least two radio frequency signal generators is directly connected to an input of the power combiner by a cable bound connection and the radio frequency receiver is connected to an output of the power combiner by a cable-bound connection, such that the artificial radio frequency signals generated by the at least two radio frequency signal generators are combined by the power combiner, thereby obtaining a combined signal that is forwarded to the radio frequency receiver.
