摘要： A method for transmitting data advantageously reduces cross-talk in high-speed data transmission. The method comprises receiving an input data word, encoding the input data word into a code word, and driving the code word on to an interconnect for transmission. The code word is generating using a balanced coding scheme, and the interconnect is a single-ended, twisted-wire on-chip fly-over interconnect. A receiver circuit decodes the code word to generate an output data word.

摘要： A crosstalk emulator for a cable, preferably a xDSL telecommunication cable, represented by several emulation paths each comprising a first segment (L1a/L4a) serially connected to a second segment (L1b/L4b) on a printed circuit board PCB. The first and second segments of a same emulation path form an angle, e.g. of about 90 degrees, at their junction point. All the emulation paths have a same length and preferably run in parallel over the PCB. As a result, each emulation path crosses only once (X21) any other emulation path at a cross-point. Furthermore, the area occupied by the crosstalk emulator on the PCB is reduced with respect to a matrix topology, whereby the present topology can easily be extended to large numbers of couplings, allowing design guidance for a passive coupling emulator with a large amount of coupling elements (CP) at the cross-points.

摘要： A method and system of compensating for distortion in a baseband in-phase (I) and a corresponding baseband quadrature (Q) signal. The circuit includes an in-phase I attenuator configured to attenuate the baseband in-phase I signal and an in-phase Q attenuator configured to attenuate the baseband Q signal. There are one or more circuits that are configured to receive the attenuated in-phase I signal and the attenuated baseband Q signal. Each circuit performs a different calculation based on predetermined equations configured to determine the IM2, HD2@0°, HD2@90°, IM3@0°, IM3@90°, HD3@0°, and HD3@90°. The distortion compensation circuit is configured to use the result of at least one of the calculation circuits to generate I and Q distortion compensation signals.

摘要： Embodiments of the present invention relate to a method and an apparatus for sending a single-ended loop testing SELT measurement signal, and a control device. The method for sending a SELT measurement signal includes: aligning a synchronization symbol of a digital subscriber line on which a SELT diagnosis needs to be performed with a synchronization symbol of at least one DSL line for data transmission, where the synchronization symbol of the digital subscriber line on which a SELT diagnosis needs to be performed and the synchronization symbol of the at least one digital subscriber line for data transmission are uplink or downlink synchronization symbols; and carrying a SELT measurement signal over the aligned synchronization symbol of the DSL line on which a SELT diagnosis needs to be performed, where the SELT measurement signal is used to detect transmission quality or a line fault of the DSL line.

摘要： A transmitter and a receiver of a multiple input multiple output (MIMO) communication system may use two codebooks to share channel information. When the transmitter uses eight transmit antennas, two codebooks may be defined. When the receiver generates two precoding matrix indicators from two codebooks, a combination of the two precoding matrix indicators may indicate a single precoding matrix. Precoding matrix candidates may also be defined.
