中文摘要：
该文研究了一种基于误差符号反馈的自适应预编码器设计算法,以用于抑制下行传输中的串音干扰。此算法相对传统自适应算法而言,运算复杂度低,占用上行链路数据量小。该文分析并比较了此最小均方准则算法和基于误差符号反馈的正交准则预编码算法。计算机仿真结果表明,此算法收敛,并且收敛速度优于正交准则预编码算法。
英文摘要：
In this paper, an adaptive preeoding design algorithm based on error symbol feedback is studied which is used for downlink transmission crosstalk suppression. Compared with conventional adaptive algo- rithms, the＇computational complexity of this algorithm is low, taking a small amount of uplink data. This paper analyzes anci＇eompares ihe minimum＇ mean;squar＇e error＇critenon sign feedback algorithm and the orthogonal criteria for pre-encoding algorithm. Computer simulation results show that this algorithm convergenees and speed of convergence is： better than the orthogonal precoding algorithm.
