tap weight-
The proposed algorithm lows the complexity by choosing decision delay in advance and then making solution of the equalizer tap coefficient, a new decision delay choice method is proposed, solution by using weight method, diagonal matrix transform, z extension and a new energy restrictive condition which restrains noise enhance, a new decision delay choice method is proposed, the simulation result shows that the proposed algorithm has better equalization effect and enhanced performance comparing to the general mmse algorithm, simulation research on the precision and dynamic scope of parameters in digital realization time domain equalization algorithm, design software and hardware of time domain equalizer. fourthly, there exist a lot of interfere in dsl line, especially, dsl works in multi - user mode, the near end interference is serious
通過先選擇判決時延，再進行時域均衡器抽頭系數求解的方法降低了時域均衡計算復雜度；對于均衡器抽頭系數的求解使用了加權技術，通過對角矩陣變換， z擴展，使用不同的能量約束條件對演算法求解，結果表明這種約束有效的抑制了噪聲增強，與常用刪se比較，該演算法有更佳的均衡效果，演算法性能得到了提高：論文還對數字化實現時域均衡演算法中每一部分參數的精度、變量的動態范圍進行了模擬研究，對時域均衡的軟硬體實現進行了設計。
