Systems and methods are described for transmitting data over physical channels to provide a high bandwidth, low latency interface between a transmitting device and a receiving device operating at high speed with low power utilization. Communication is performed using group signaling over sets of four wires using a vector signaling code, where each wire of a set carries a low-swing signal that may take on one of four signal values. Topologies and designs of wire sets are disclosed with preferred characteristics for group signaling communications.

Embodiments of the present application disclose a communication method and a communication node for device-to-device (D2D) direct communication, and relate to the field of D2D technologies. The method comprises: receiving, by a first node, an interference signal from an interference node; and sending, by the first node, the interference signal and a to-be-sent signal in a manner in which the interference signal and the to-be-sent signal can be received by at least one second node.

A signal interface unit for a distributed antenna system includes a channelized radio carrier interface configured to communicate an uplink channelized radio carrier for a radio frequency carrier to a channelized radio carrier base station interface; an antenna side interface configured to receive an uplink digitized radio frequency signal from the distributed antenna system communicatively coupled to the antenna side interface; and a signal conversion module communicatively coupled between the channelized radio carrier interface and the antenna side interface and configured to convert between the uplink digitized radio frequency signal and the uplink channelized radio carrier at least in part by adjusting at least one uplink attribute of the uplink digitized radio frequency signal received from the distributed antenna system to comply with requirements of the channelized radio carrier base station interface.

An electronic device includes a signal sender that sends a pair of transmission signals of mutually opposite phases to an external device via a pair of transmission paths. The signal sender differentiates each amplitude of the pair of transmission signals.

Power line carriers (PLCs) are susceptible to transients and electromagnetic interference (EMI) on the power line. To address transients and EMI on the power line, an improved power PLC involves transmitting a signal over the power line using a controlled current source, where the current source is modulated by the signal. The current source output is designed to be independent of the voltage on the power line and the load, and thus, is less susceptible to transients and EMI on the power line. The system architecture of the improved PLC also allows for simple, predictable, and flexible termination. In an example implementation in the automotive industry, the improved high frequency PLC may provide a low cost replacement for existing communication interfaces. The improved PLC may consolidate system in-vehicle communication, reduce in-vehicle wiring, provide system flexibility, and decrease vehicle weight and system cost.

The present invention provides a semiconductor device realizing suppression of increase in consumption power. A semiconductor device has a signal line, a reception buffer circuit which is coupled to an end of the signal line and to which a signal is supplied from the signal line, and a delay element which is wired-OR coupled to an end of the signal line and shapes a waveform of a signal at the end of the signal line.

The disclosed embodiments relate to the design of an equalizer that uses both cross-coupled cascodes and inductive peaking to reduce distortion in a signal received from a communication channel by attenuating lower frequencies and amplifying higher frequencies. At lower frequencies, when the effects of inductive impedance within the equalizer are negligible, the equalizer essentially functions as a traditional cascode amplifier that presents high gain. At higher frequencies, the increases in inductive impedances within the equalizer act to boost a gain of the equalizer.
