摘要： An apparatus for the transmission of information along a noisy DC power line. The apparatus includes one or more interface modules, each of which provides an interface for receiving a high bit-rate digital information signal corresponding to a human voice, music, or a video. The apparatus further includes a channel coder connected to the interface modules for processing the high bit-rate digital information signals to produce a verifiable digital signal which includes information for performance of an error correction to compensate for background noise. The apparatus also includes a modulator connected to the channel coder for converting the verifiable digital signal to an analog signal. Finally, the apparatus includes a transmitter connected to the modulator for transmitting the analog signal along the DC power line.

摘要： A method of wireless communication uses a fiber composite structure including a first conductive fiber composite layer comprising carbon fiber, a second conductive fiber composite layer comprising carbon fiber, and an insulating layer electrically isolating the first composite layer from the second composite layer. Communication devices such as transceivers are connected to the first and second composite layers and signals may be communicated to and from the communication devices through the composite layers. An AC or DC voltage may be applied to the first and second composite layers to conduct electrical power to the electrical devices without the requirement of separate wires.

摘要： The present invention relates to a system and method for signaling among a plurality of devices via a communication carrier over a noisy medium such as a power line and particularly relates to an innovative method and system for high speed signaling using an innovative modulating scheme. The scheme is particularly well adapted for signaling over multiple channels and over direct current (DC) power lines. At the transmitter end, a modem modulates data to be transmitted according to a modulation scheme and a signaling shifter modifies the carrier according to a modification scheme. At the receiver end, a modem demodulates the data according to the modulation scheme and a detector detects the signal in accordance with the modification scheme. Signals may be received over multiple channels. A signal is sent over a subset of the channels. Remaining channels can be used for competing signals avoiding interference. The channel chosen for sending a signal may also indicate signal priority. An innovative device is presenting for testing communication over DC power lines with adjustable attributes.
