A sensor device includes: a detection device that detects a predetermined physical quantity and converts the physical quantity into a detection signal; a communication device that is to be connected to a controller through a first line and a second line, performs at least one of reception from the controller or transmission to the controller by a differential transmission method and, based on a request signal received from the controller, transmits the detection signal generated by the detection device; and a conductive shield member that is applied with a constant potential and covers the detection device and the communication device. The conductive shield member reduces radiation noise generation and simplifies the sensor device structure.

A transceiver is disclosed which includes a transmitter and a receiver. The transmitter provides an impairment measurement signal, which is substantially similar to a transmitted communication signal except for a possible difference in phase and/or a magnitude, to the receiver. An envelope detector within the receiver provides an envelope of the impairment measurement signal to the transmitter. The transmitter determines sets of one or more filtering coefficients using the envelope of the impairment measurement signal and adjusts phases or magnitudes and/or phases of a sequences of bits used to generate the transmitted communication signal in accordance with the sets of one or more filtering coefficients to compensate for the unwanted distortion and/or the unwanted interference present within the transmitted communication signal.

A device for communication includes a receiver and a tuned infinite impulse response (IIR) compensation filter. The receiver is coupled to an in-phase path and a quadrature path. The tuned IIR compensation filter is coupled to one of the in-phase path or the quadrature path.

A multi-carrier communication system such as an OFDM or DMT system has nodes which are allowed to dynamically change their receive and transmit symbol rates, and the number of carriers within their signals. Changing of the symbol rate is done by changing the clocking frequency of the nodes' iFFT and FFT processors, as well as their serializers and deserializers. The nodes have several ways of dynamically changing the number of earners used. The selection of symbol rate and number of earners can be optimized for a given channel based on explicit channel measurements, a priori knowledge of the channel, or past experience. Provision is made for accommodating legacy nodes that may have constraints in symbol rate or the number of carriers they can support. The receiver can determine the correct symbol rate and number of earners through a priori knowledge, a first exchange of packets in a base mode that all nodes can understand, or an indication in the header of the data packet which is transmitted in a base mode of operation that all nodes can understand.

A PLC modem (131-133) is prompted to increase, starting from a predetermined minimum transmit power, a transmit power of data transmission on a PLC channel (112) at a given time or time period defined with respect to a mutual time reference of a DSL channel (111) and the PLC channel (112). A DSL modem (121) is prompted to measure a signal-to-noise value at the given time or time period defined with respect to the mutual time reference. Mitigation of interference 190 between the PLC channel (112) and the DSL channel (111) becomes possible.

Aspects of the disclosure relate to a configurable subframe structure for use in next generation (e.g., fifth generation or 5G) wireless networks utilizing a time division duplex (TDD) carrier that minimizes interference with adjacent legacy wireless networks. The configurable subframe structure may be configured to produce next generation subframes, each including at least one of a downlink portion or an uplink portion, to substantially align downlink portions with corresponding legacy downlink subframes and/or uplink portions with corresponding legacy uplink subframes.
