摘要： A self-learning and/or self-adjusting communication controller and/or optimizer uses operational data collected from a communication system to adjust operation of the communication system to changing operational, environmental, etc. conditions and, in some embodiments, to customize operation of the communication system's lines and components so that their performance can be controlled, improved and/or optimized. In various embodiments, operational parameters and/or rules are established and/or adjusted based on information obtained from the system concerning the system's operation; information regarding margins used by a DSL system and code violation counts reported by the DSL system are used to set margin levels for one or more line sets (each line set including an individual line, a group of lines, a binder, etc.) and/or other users and/or components of the DSL system; and, the controller and/or optimizer forces a small number of test lines into as yet unexperienced and/or unimplemented operational conditions so that new knowledge can be obtained.

摘要： Precoding mitigates or removes interference signals (especially crosstalk) among multiple users with interconnected transmitters in vectored DSL systems and the like. Efficient implementation is provided of the R matrix in RQ factorization that characterizes multi-user downstream vector channels (such as DMT VDSL one-sided or two-sided transmission channels). A set of precoder coefficients can vary with each tone used by each user and depend upon the encoding order of users selected for each tone. In adaptive operation, the coefficients of the R and Q matrices can be updated when changes occur to the transmission environment. Variable modulo arithmetic mitigates the power-enhancement problem, and the base of modular arithmetic also can vary with each user within a single precoder for a single tone. The user order of preceding need not be the same on each tone, and the modular arithmetic progression may thus also be different on each tone because multi-user situations create an unusual situation for precoding in that the modulo arithmetic used for each user can be different (thus imposing a larger power increase) and because digital duplexed or synchronized DMT systems can separately implement a precoder for each tone. Further, the precoding process terminates each DMT symbol, after processing up to the total number of users. An optional dither signal, known to both transmitter and receiver, can be added at the transmit side and removed at the receiver side to smooth the precoding process and ensure that aberrations in the transmitted constellation size and characteristics are consistent despite any unusual variations in the feedback signal that exits the feedback filter matrix G before being subtracted from the user signal of interest. Some embodiments use a “subtraction only” mode while other embodiments use a dither signal and/or modulo arithmetic, though embodiments of the present invention do not require use of identical constellations by both transmitter and receiver.

摘要： The present invention provides, in one embodiment, a method of simplifying filtering with respect to a band plan. The method includes selecting a reflection point relative to the band plan and designating subchannels as unusable within a filterable separation of the reflection point that would otherwise introduce an asymmetry within the filterable separation. The present invention also provides a filtering simplifier for use with a DSL system having a band plan. The filtering simplifier includes a reflection point selector configured to select a reflection point relative to the band plan. The filtering simplifier also includes a subchannel designator coupled to the reflection point selector and configured to designate subchannels as unusable within a filterable separation of the reflection point that would otherwise introduce an asymmetry within the filterable separation.

摘要： A semi-distributed method of managing the spectral power over multiple digital subscriber line communication loops (LP1, LP2) is disclosed. A central office (CO) DSL transceiver (10) and a remote terminal (RT) DSL transceiver (15) communicate with customer premises equipment (CPE) (121, 122) over separate twisted-pair wire loops (LP1, LP2) that are in sufficient physical proximity with one another as to suffer from crosstalk. A network management center (NMC) (20) initializes a price parameter, which is used by the CO (10) and RT (15) in independent maximization problems. The CO (10) derives a maximum tolerable power spectral density for the RT (15) that permits the CO (10) to reach a target data rate, and the RT (15) derives an actual power spectral density that maximizes its data rate, each using the price parameter. The NMC (20) compares the actual RT power spectral density to the tolerable RT power spectral density, and adjusts the price parameter accordingly, with the process repeating until convergence. As a result, the RT data rate is maximized to a level that still permits the CO (10) to reach its target data rate, thus maximizing the overall network data rate.

摘要： Estimates of a communication system configuration, such as a DSL system, are based on operational data collected from a network element management system, protocol and users. The operational data collected from the system can include performance-characterizing operational data that typically is available in the OSL system via element-management-system protocols. Generated estimates and/or approximations can be used in evaluating system performance and directly or indirectly dictating/requiring changes or recommending improvements in operation by transmitters and/or other parts of the indication system. Data and/or other information may be collected using internal means or using system elements and components via e-mail and/or other extra means. The likelihood of the models accuracy can be based on various data, information and/or indicators of system performance, such as observed normal operational data, test data and/or prompted operational data that shows operating performance based on stimulation signals.

摘要： Control of a digital communication system having a plurality of communication lines on which signals are transmitted and received is implemented using a variety of methods and systems. According to one embodiment of the present invention, a method is implemented where the signals are affected by interference during transmission and each of the communication lines has at least one transmitter and at least one receiver. A model is created of the interference characteristics due to the signals carried on the communication lines. Interference characteristics for a line are determined based on the model and actual signals carried on other communication lines different from the line for which the characteristics are being determined. Actual interference is compensated for on the communication line using the determined interference characteristics.

摘要： Configuration or otherwise controlling parameters of a Digital Subscriber Line (DSL) system related to power, band usage and margin is based on collected operational data. Operational data are collected from at least one DSL system operating under a known configuration and/or a profile. A target profile is selected based on binder-level information. The collected operational data is analyzed and conditions for changing the DSL system configuration to the target profile are evaluated, including any applicable transition rules pertaining to changing profiles. If the conditions hold, then the DSL system is instructed to operate with the target profile. Binder-level information can include deployment point information, topology information, and/or crosstalk coupling information. The controlled parameters may have values that are chosen using one or more spectrum balancing methods. Such spectrum balancing methods may be executed infrequently, and may make use of all binder-level information that is available.

摘要： Loading and ordering techniques are provided for one-sided and two-sided vectored line groups, as well as loading methodologies that also can be used on a single line, in communication systems such as Digital Subscriber Line (DSL) binders. In particular, a method for loading bits into a plurality of lines in a vectored DSL system using Discrete MultiTone (DMT) modulation is disclosed. The method iteratively determines two or more of the following sequentially: line ordering for each tone; power spectral density for the transmitted signal of each line; and bit allocation for the signal of each line. In some embodiments, line ordering may include order-swapping which may assign a first line to a first initial position, assign a second line to a second initial position, move the first line to the second initial position, and move the second line to the first initial position.

摘要： A butterfly processor architecture including a single high speed multiplier unit and two adder/subtracter units structured to efficiently perform radix-2 decimation-in-time (DIT) butterfly operations is disclosed. The computations for windowing operations, FFT operations, and IFFT operations may be realized in terms of butterfly operations. Therefore, the butterfly processor architecture may be used to perform the computations of a plurality of signal processing operations. The butterfly operations may be performed in-place whereby the results of each operation may be stored in the same location in memory where the inputs for each operation were retrieved. Performing the butterfly operations in-place ensures that the memory may be big enough to hold one frame of data. The butterfly processor architecture may also use scaling elements for implementation of a dynamic scaling algorithm which may reduce the precision requirements of intermediate results when performing signal processing operations and may reduce the data word length.
