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.

摘要： The present invention refers to a method for defining useable frequency bands for a powerline communication (PLC) system (101) using power supply lines of a power supply network (104a) for interconnecting a number of PLC nodes (302, 306) such that electromagnetic emissions generated by PLC signals (s(t)) transmitted via said power supply lines do not interfere with broadcast RF signals radiated in the same frequency bands. Before starting own communication activities, PLC nodes (302, 306) participating in a PLC session scan (S1a) the entire frequency range designated for powerline communication to detect (S1b) frequency bands which are occupied by broadcast services. During powerline communication the occurrence of broadcast signals is regularly checked (S2) by screening (S2a) the entire frequency range designated for powerline communication and detecting (S2b) relevant broadcast bands that should be omitted during powerline communication to avoid interference noise (n(t)). After that, new frequency bands for powerline communication are allocated (S3) within said frequency range, provided that these new bands are not occupied by any detected wireless service.

A mains filter (220) provides a filter path between each of its first ports (221) and a corresponding one of second ports (222), wherein each first port (221) is connected to one of the first connectors (211). Each second port (222) is connected to one of three or more second connectors (282) of an AC power socket (280). A power line communication unit (250) is connected with each of the first ports (221) and transmits and/or receives data according to a transmission method using more than one transmission channel between two devices connected via the mains distribution network. The mains filter (220) improves PLC transmission quality by suppressing disturbances generated by the appliances and reduces PLC stray radiation.
