分析了基本E-脉冲法的缺点。针对缺点提出了一种新的利用纠错编码原理实现的改进E-脉冲法。首先，进行了基本理论推导，在理论推导的基础上，给出了改进E-脉冲法的基本原理以及实现系统方框图。然后，应用该方法进行了模拟仿真实现。利用实验中提供的极点数据，对回波进行纠错，实验结果表明该方法是正确的、有效的。

In this paper, a new theory which is based on error-correcting code theory is proposed to overcome the deficiencies of E-pulse is analyzed. First, the fundamental theory is derived. On the basis of theoretical derivation, the new theory and the system block diagram are proposed. Then, the method is used for simulation experiment. The experiment uses the number to correct the back wave. The experiment results prove that this method is correct and effective.
