    摘要： A method and apparatus for a multiple channel communication device training, and processing utilizing a transmit signal power control operation. Multiple channel communication devices utilize inter-channel crosstalk mitigation techniques, such as MIMO processing modules or MIMO precoding systems, to cancel unwanted crosstalk coupling across active and provisioned channels. Upon provisioning and activation of a new channel that connects to the multiple channel communication device the signal on the new channel couples into other channels and the existing MIMO filtering or processing structure is untrained to mitigate the crosstalk from the new channel. A power control training operation prevents crosstalk from hindering operation on other channels during the training operation. During one example training operation, the power level of a transmit signal is incrementally increased as the crosstalk cancellation filter(s) are trained.

    摘要： A method and apparatus is disclosed for processing two or more encoded signals received over a multi-channel communication system to cancel or mitigate coupling and the effects of the channel on the two or more encoded signals. In one embodiment a multi-channel communication system utilizes DMT processing and some form of encoding, such as block coding or convolutional coding. To recover the transmitted signal, processing in the receiver may comprise MIMO processing in conjunction with decoding. The MIMO processing may be configured with decision directed processing to thereby generate one or more cancellation signals based on isolated error terms. Decoding occurs on encoded signals after MIMO processing. Memory may be interspersed or available throughout the system to store incoming symbols that have not yet undergone decoding and MIMO processing. Decoding and MIMO processing may occur sequentially through the channels.

    摘要： A method and apparatus is disclosed for processing two or more signals received over a multichannel communication system to cancel or mitigate coupling and the effect of the channel on the two or more signals. In one embodiment a multichannel communication system utilizes DMT processing to transmit two or more signals over two or more channels. To recover the transmitted signal, processing in the receiver may comprise submitting the two or more signals to a matrix filter configured to cancel the effects of the channel, such as phase and magnitude distortion, and account for self FEXT. In addition, decision directed processing may occur, generating one or more cancellation signals based on the noise on the output of the matrix filter. By filtering the noise terms and generating a crosstalk compensation signal, the transmitted signal is recovered more faithfully and the performance of the communication system is improved.

    摘要： A method and apparatus in which a Tap-Weight Computer (TWC) calculates a Tap-Weight Vector (TWV) are provided. The TWV is coupled to a register in an adaptive filter module. Each adaptive filter module includes several adaptive filters that each include a tapped delay line. The input to the tapped delay line is one of a plurality of potential interfering signals. The TWV controls the weighting of the outputs from the taps off the delay line. The weighted outputs from each tapped delay line are subtracted from a received signal which potentially includes interference from the potential interfering signals. The TWC is multiplexed to each of the plurality of adaptive filters so that each adaptive filter is loaded with a TWV calculated by the TWC to reduce the amount of interference contributed by a particular potential interfering signal coupled to an input to that particular adaptive filter.
