摘要： A network analyzer device, including a control unit configured to determine network topology information related to impedance mismatches in a voltage distribution network on the basis of an evaluation of measured signals received from the voltage distribution network in response to probe signals supplied to the voltage distribution network and/or phase or running time information about noise signal components generated by appliances connected to the voltage distribution network and received by the network analyzer via different receiving paths. The network analyzer device outputs network information related to impedance mismatches in the voltage distribution network, wherein the output network information contains information about a total number of the impedance mismatches, wiring lengths between impedance mismatches, and characteristics of the impedance mismatches.

摘要： In a communications device a grouping unit uses channel state information when mapping data bits to a plurality of different constellation groups. Each constellation group is assigned to another modulation scheme. A plurality of sub-carriers is assigned to none or one of the constellation groups and each modulation uses another one of the constellation groups. The communications device includes at least one scalable interleaver unit, wherein each interleaver unit is assigned to one of the constellation groups and interleaves the assignment of data bits mapped to each constellation group and the sub-carriers that carry a symbol information derived from the data bits. As an example, the interleaver unit performs frequency interleaving by interleaving, at constellation level, the sub-carriers that carry the symbol information.

摘要： A communications system includes a receiver unit connected with a transmission channel. The receiver unit determines a signal power of a first communications signal received over the transmission channel. A transmitter unit is connected with the transmission channel and transmits a second communications signal, wherein a gain of the communications signal being output by the transmitter unit is controllable. A control unit controls the gain of the transmitter unit in response to the determined signal power. At the receiver unit, detection of broadcast signal ingress during data communication is improved and methods for avoiding disturbances between coexisting communications systems may become more reliable. Different distances between successive training symbols suitable for channel estimation may be provided to enhance the noise measurement.
