基于对角块分解的下行方向快速预编码算法
摘要
利用同一电缆包中布线的空间特殊性
提出一种抑制下行传输方向串音的预编码算法。一方面由于算法中仅涉及二阶矩阵的逆
运算量很小
易于实现。另一方面
此方法性能优于之前提出的一阶逼近算法
而与三对角线逼近算法性能相近
但运算量要小得多。基于实测数据的计算机仿真验证了结果的正确性。
Abstract
Based on special line position
a novel precoder of cancellation crosstalk for downstream transmission was proposed.As the new method needs only two order matrix inversion
the precoder had a much lower computational com-plexity and was easy for implementation.In addition
the performance of the precoder was superior to that of the first or-der algorithm
almost the same tri-diagonal precoder.Computer simulation results based on real measured data verify the efficiency of the proposed precoder.
