摘要： An access node of a communication system comprises a plurality of transmitters adapted for communication with at least one receiver over a plurality of channels. The access node is operative to obtain estimated crosstalk coefficients between a joining channel and an active channel, and to set a power level of at least one signal transmitted over the joining channel based on the estimated crosstalk coefficients. The access node obtains the estimated crosstalk coefficients by first obtaining a subset of the estimated crosstalk coefficients and subsequently determining additional ones of the estimated crosstalk coefficients by applying an interpolation process to the estimated crosstalk coefficients in the subset. The access node sets the power level of the signal transmitted over the joining channel in a manner that ensures maintenance of a desired performance characteristic for the active channel.

摘要： A method, a system, and a device for power adjustment are provided. The method includes: determining whether transmission power of a line needs adjustment according to feedback errors during a training procedure of a Vectored-Digital Subscriber Line (Vectored-DSL) filter; and adjusting the transmission power when the transmission power of the line needs adjustment. By automatically determining whether the transmission power needs adjustment during a training procedure of a precoder or canceller, and adjusting the transmission power automatically when the transmission power needs adjustment, interference to other subscribers caused by the precoder or canceller during the training procedure is reduced, and call drops of the other subscribers are prevented.

摘要： Crosstalk between subscriber loops used to transmit different broadband services through the same bundled telephone cable is a significant limitation to providing digital subscriber line services. A method for estimating the crosstalk, identifying the sources of the crosstalk and predicting additional sources of crosstalk are disclosed. The crosstalk sources are identified in the frequency domain by maximizing the correlation with a “basis set” of received crosstalk PSDs which consist of the cascade of a finite set of known transmit PSDs types times a representative set of crosstalk couplings. Multiple crosstalk types are identified with a technique of successive spectral subtraction. Once a type is identified the crosstalk disturber is compared against all other members of the complete set for that type. Additionally, Multiple Regression (MR) techniques and a Matching Pursuit (MP) algorithm are used to increase the ability of the system and method to identify various crosstalk disturbers. The identification of the crosstalk disturber is then used to perform crosstalk cancellation and spectrum management in a DSL system.

摘要： A multi-carrier information transceiver that exhibits robustness against radio frequency interference (RFI) signals present in the communications channel. The transceiver includes a RFI mitigation technique that operates not only during the steady state operation of the transceiver but also during the training stage of the transceiver. That requires dynamically modifying the training signals when the presence of RFI is detected. The modification of the training signals facilitates the estimation of RFI, improving the performance of the multi-carrier transceiver.

摘要： A novel mechanism for sharing filter taps across a plurality of interference cancellers. Each interference canceller may be directed to impairment, such as Ethernet impairments, including Ethernet 1000Base-T impairments. Various interference impairments include echo cancellation, NEXT cancellation and/or other interference detection or cancellation, etc. The hardware requirements of the interference impairment cancellers are reduced by sharing filter taps among the cancellers. In a first embodiment, the taps from a unified filter tap bank are shared across all the interference impairment cancellers for all four channels and over all ports. In a second embodiment, a portion of the taps of each filter are shared wherein each canceller comprises a fixed filter tap portion and a shared filter tap portion. A tap allocation algorithm assigns taps to those cancellers that need them the most. A canceller configuration is selected that yields maximal interference mitigation and the taps are allocated accordingly.
