Abstract: In accordance with an embodiment, the method includes inserting a plurality of crosstalk probing signals within the wired multi-carrier communication system for probing the crosstalk from respective ones of the plurality of disturber lines into the victim line, carrying out crosstalk measurements over the victim line, and estimating the crosstalk coefficients from the crosstalk measurements. The method further includes organizing the plurality of disturber lines into subsets of disturber lines, and individually assigning disjoint groups of carriers to the respective subsets of disturber lines. The insertion of the plurality of crosstalk probing signals is confined within the respectively assigned groups of carriers. The subsets of disturber lines and/or the groups of carriers used for a second or subsequent iteration are tailored based on crosstalk characteristics observed for the respective disturber lines during a pervious iteration.

Abstract: In one embodiment, the line termination card includes a data output terminal configured to output a data sequence. The card further includes a vectoring entity configured to parse and encode the data sequence into frequency samples according to a carrier loading parameter, configured to scale the frequency samples into scaled frequency samples according to a carrier scaling parameter, and, configured to process the scaled frequency samples for crosstalk compensation. A controller is configured to adjust the carrier loading parameter and the carrier scaling parameter, and a forwarder is coupled to the data output terminal and to the controller. The forwarder is configured to forward the data sequence, the carrier loading parameter and the carrier scaling parameter towards a further line termination card.

Abstract: A method and apparatus for frame synchronization in digital communication systems using multiple modulation formats perform a search for a differential frame alignment sequence (FAS) to frame-align the received digital stream and determine the polarity of the stream. Embodiments of the invention are compatible with Differential Phase Shift Keying (DPSK), Duobinary Signaling (DBS), and ON/OFF Keying (OOK) modulation formats.

Abstract: Bit error patterns for high speed data systems are generated by randomly distributing a first error pattern of G bits, output from a group of substantially uncorrelated bit error generators, into a second error pattern of N bits, where G and N are integers and G is less than or equal to N. In one embodiment, G bit error generators produce a G bit error pattern per bit period. Each bit error generator operates at a prescribed bit error rate. A distribution element randomly rearranges the order and placement of the G bits produced during a single bit period within an N bit grouping. The N bit group corresponds to N consecutive bits of data with which the error bits can be combined. Each bit error generator can be realized by a linear feedback shift register or its equivalent. Different primitive polynomials and different lengths can be used for each linear feedback shift register. In addition, outputs from fewer than all the shift register stages are utilized to generate each error bit.
