Abstract: Systems and methods for partial self-FEXT (far-end crosstalk) are described. One method, among others, comprises determining one or more instantaneous characteristics of an input signal, wherein the one or more instantaneous characteristics comprise one or more of amplitude of the input signal and an energy level of the input signal. The method further comprises selecting one or more disturbers to cancel according to the one or more instantaneous characteristics, wherein selecting one or more disturbers is performed on a per-DMT (discrete multi-tone) symbol basis.

Abstract translation: 描述了部分自FEXT（远端串扰）的系统和方法。 一种方法包括确定输入信号的一个或多个瞬时特性，其中一个或多个瞬时特性包括输入信号的幅度和输入信号的能级中的一个或多个。 该方法还包括根据一个或多个瞬时特性选择一个或多个干扰器来取消，其中，对每个DMT（离散多音调）符号进行选择一个或多个干扰器。

Abstract: A method implemented in a multi-user communication system is described for performing far-end crosstalk (FEXT) cancellation for each victim user. The method comprises performing dynamic programming to allocate resources according to (N−1) normalized disturber coupling values and difference rate function values associated with N total users in the system involved in partial FEXT cancellation. In accordance with some embodiments, dynamic programming comprises selecting a tone and one or more disturbers to be cancelled for the tone.

Abstract translation: 描述了在多用户通信系统中实现的方法，用于为每个受害者用户执行远端串扰（FEXT）取消。 该方法包括执行动态规划以根据涉及部分FEXT消除的系统中与N个总用户相关联的（N-1）标准化干扰耦合值和差分率函数值来分配资源。 根据一些实施例，动态规划包括选择音调和要为音调取消的一个或多个干扰器。
