Binary data is processed through a differential pre-encoder, which includes a simple modulo-2 addition. This step is used to cancel the propagation error that can be introduced by duo-binary modulation and to simplify demodulation. Next the duo-binary encoder introduces controlled Inter Symbol Interference between a previously sent bit and a present bit to compress the spectral density closer to the DC. Next a 60-GHz carrier is modulated and transmitted over differential transmission lines.

A method and corresponding set-up system arrangement are provided for actuating execution units. A communication node is further provided which is suitable for use in the method or in the system arrangement. Also provided is a computer program comprising control commands which implement the proposed method or operate the proposed system arrangement.

A communication system includes a digital data processor that produces a digital data sample and one or more control bits. A serialized transmit interface combines the digital data sample and the control bit(s) into one or more data packets and sends the data packet(s) over a signal line. A serialized receive interface receives the transmitted data packet(s) from the signal line and produces a reconstructed digital data sample and the control bit(s) from the transmitted data packet(s). A control circuit coupled to the serialized receive interface produces a control signal from the control bit(s). The communication system may include a converter circuit, which produces an RF input signal by performing a digital-to-analog conversion of the reconstructed digital data sample, and by upconverting the resulting analog data sample signal to RF. A power amplifier amplifies the RF input signal and modifies operation of a sub-circuit based on the control signal.

A method for transmitting digital subscriber connection signals to an interface of an end user via a coaxial cable includes: supplying, by a distribution point unit (DPU), first balanced subscriber connection signals to the coaxial cable by a first transformation; coupling unbalanced subscriber connection signals into the coaxial cable into a lower frequency range of an overall frequency range; attenuating, by means of a filtering device, a reflection of the unbalanced subscriber connection signals in the coaxial cable; a second transformation of the unbalanced subscriber connection signals into second balanced subscriber connection signals by means of a balun device assigned to the interface, wherein the input impedance of the filtering device is adjusted with respect to reflections from the direction of the customer terminal output; and separately making the second balanced subscriber connection signals available at the customer terminal output.

In certain embodiments, an assembly has intermediate pods magnetically, but not galvanically, coupled along an electrically conductive cable. Each pod has a magnetic core surrounding and inductively coupled to the cable and one or more coils inductively coupled to the magnetic core. The pod transmits, for example, outgoing current pulses on the cable by inducing electrical signals in the cable using a transmitter coil and the magnetic core. In addition, the pod repeats, for example, incoming current pulses on the cable by inducing electrical signals in the cable using the transmitter coil and the magnetic core, based on electrical signals induced in a receiver coil via the magnetic core by the incoming current pulses. Such an assembly can function as a data collection system for scientific research and/or as an early-warning system for events, such as earthquakes and tsunamis, without having to modify the cable itself.
