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： 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.
