Abstract: The present disclosure concerns a method of processing measurement data. The method includes gathering measurement data by a measurement component, processing the measurement data by the measurement component, thereby producing at least one two-dimensional histogram of a measurement quantity depending on a variable for at least one period of time, forwarding, by the measurement component, the at least one two-dimensional histogram to a processing component, and processing, by the processing component, the at least one two-dimensional histogram received from the measurement component, thereby generating data associated with at least one histogram and data associated with a waterfall diagram having several waterfall lines, wherein each of the several waterfall lines is associated with an individual histogram. Further, the present disclosure concerns a system for processing measurement data.

Abstract: A method of decoding multiple transmissions of time related data is provided. The method comprises receiving and recognizing separate data blocks, each data bock having data that comprises at least a code word assigned to a system frame number that depends on the transmission time of the respective data block; demodulating each data block in order to obtain IQ-samples, likelihood ratios or representatives thereof for each data block; accumulating the IQ-samples, likelihood ratios or representatives thereof to a sum that is forwarded to a single-block decoder; and decoding the sum, thereby obtaining decoding results. Further, a device for decoding multiple transmissions of time related data as well as a method of verifying a device for decoding multiple transmissions of time related data are described.

Abstract: A method and a system are provided for channel detection like radio frequency channel detection in modern telecommunication standards like 5G-NR (new radio). The method and the system provide a fast and sensitive channel detection by evaluating a radio frequency signal received. The respective method and system may be applied to different telecommunication standards, for example new telecommunication standards like 5G-NR (new radio) and LTE.

Abstract: A method for identifying a radio frequency transmitter is described, wherein a radio frequency signal is received via a radio frequency channel, the radio frequency signal including at least one radio frequency sequence. The sequence received is split into a plurality of chunks. The radio frequency channel is equalized by using a first subset of the plurality of chunks. The amplitude of each chunk of a second subset of the plurality of chunks is measured in the equalized radio frequency channel. The at least one amplitude is used for deciding whether the at least one sequence of the radio frequency signal corresponds to a sequence listed in a list. Further, a system for identifying a radio frequency transmitter is described.

Abstract: A method for tamperproof identification of individual electronic sub-assemblies determines the state changes of specific memory cells of the memory resulting from a specific interruption of one or more auxiliary functions of a memory of an individual electronic sub-assembly and compares them with respect to identity with predetermined memory-characteristic reference state changes of specific memory cells of the memory resulting from the specific interruption of the auxiliary function of the memory of the electronic sub-assembly.

Abstract: In order to determine the complex pulse response of a radio channel, for instance in a digital mobile radio network, signal portions of the wanted signal transmitted via the radio channel, which signal portions are preset at the receiver end, are measured and the pulse response is then calculated from the signal portions by linear transformation.
