Method, device and system for determining a line property in the form of an arc on a power transmission line, wherein at least one test signal is coupled into the power transmission and an interference signal at an interference point, which is formed by the arc, is generated along the power transmission line with the aid of the at least one test signal, which interference signal is acquired as at least one measuring signal, and the line property is determined from the at least one measuring signal, where the line property is determined by detecting at least one intermodulation product from the at least one test signal and the mains signal of the power transmission line in the at least one measuring signal.

Method, device and system for determining an arc on a power transmission line

A method for establishing a duplex connection for data transmission between transmission units in a communications system, wherein the transmission units each have a transmit unit and a receive unit, where the duplex connection includes oppositely directed, unidirectional transmission channels, by which a communications link for each data transmission between respective transmit and receive units of the transmission units is established, during a synchronization phase transmit units independently emit in a periodically repeated manner a first synchronization signal respectively, where following detection and synchronization with the respective first synchronization signal by the respective receive unit, the respective transmit unit belonging to the same transmission unit is instructed to emit at least once a second synchronization signal respectively, where a changeover to data transmission is implemented once the second synchronization signal respectively has been detected at least once by respective receive units of the transmission units.

Cell search procedure using primary synchronization signals (PSS) and secondary synchronization signals (SSS) in a wireless communication system

A method for achieving synchronization between a transmit unit and at least one receive unit of a communications system with multi-carrier signal transmission via a transmit channel includes generating a synchronization symbol using predefined carrier frequencies, modulating the generated synchronization symbol with a predefined synchronization sequence via a transmitter to generate a synchronization signal, emitting the generated synchronization signal by the transmitter with a predefinable repetition period, the synchronization signal being utilized for transmission of an item of transmit-specific status information, receiving a signal by a receiver following transmission via the transmit channel, the received signal being formed by the emitted generated synchronization signal and transmitted repeatedly with the predefinable repetition period, and detecting and evaluating, by the receiver, the received signal via a detection algorithm, the detection algorithm determining a period of the received signal as the synchronization instant at which the synchronization signal is almost certainly present.

Method for achieving synchronization of transmit and receive units with multi-carrier signal transmission

An energy supply is provided along a route with at least one distribution station, wherein a first voltage is applied at the input and a second voltage at the output. The second voltage is lower or higher than the first voltage. A plurality of components are arranged along the route. A component, which is supplied with the second voltage, includes a power supply unit for transforming the second voltage into a third voltage.
