摘要： A description is given of an arrangement for compensation of ground offset in a data bus system comprising a plurality of communication devices (2, 10) which are each supplied with an operating voltage (U0) by a voltage source (4; 14), are connected to ground (G1); G2) and have a data bus connection (6; 12) via which they are connected to a data bus line (8). The special thing about the invention is that between operating voltage (U0) and ground (G2) at least one voltage dividing device (R3, R6) is connected whose output is coupled to the data bus connection (12) of at least one communication device (10) and whose voltage dividing ratio is selected such that an offset of the ground (G2) of the communication device (10), whose data bus connection (12) is coupled to the voltage dividing device (R3, R6), is in essence compensated compared to ground (G1) of another communication device (2).

摘要： A driver circuit includes a first inverter, a bias-control circuit, and a second inverter. The first inverter, which is connected between a first supply voltage and ground, receives an input data signal and generates an inverted version of the input data signal. The bias-control circuit, which is connected between a second supply voltage and the first inverter, receives the inverted version of the input data signal and a bias signal, and generates a level-shifted data signal based on the inverted version of the input data signal, the bias signal, and the second supply voltage. The bias-control circuit reduces a difference between voltage levels of the second supply voltage and the inverted version of the input data signal. The second inverter is connected between the second supply voltage and ground, and further connected to the bias-control circuit and first inverter and generates an output data signal.

摘要： A running disparity computation predictor is configured to analyze a frame of data, a control value, and an input tracking value and generate a predicted output tracking value. A frame selector is configured to generate an encoded frame of data based on this predicted output tracking value. A frame insertion module is configured to insert the encoded frame of data into a data stream wherein the predicted output tracking value matches an output tracking value generated by the data stream. This combination of elements can bypass an encoder built into a Hard IP block or proprietary hardware when the running disparity value is required to select control words.

摘要： In a MIMO communications system a first communications device applies beamforming to a complete transmission packet including both synchronization data and either payload data or training symbols. A second communications device evaluates the beamformed synchronization data and determines and transmits a feedback information indicating minimum required synchronization data and/or a minimum number of training symbols. The first communications device tailors the synchronization data and/or number of training symbols on the basis of the feedback information. Beamforming the complete transmission packet facilitates signal suppression at defined locations. When the channel properties change, the second communications device may provide further channel state information to adapt beamforming in the first communications device without transmission of not beamformed training symbols. The communications system may be a powerline telecommunications system.
