文档介绍：several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measuremen统的逆系统进行模拟叫做系统的逆向模拟，可以看成求一自适应系统，其传函数是未知系统的传递函数的倒数的最佳拟合，或者说求一未知系统的逆滤波系统。自适应逆滤波应用广泛，它可以作为信道均横器，在数字数据传输中，信道常等效成一个线性时不变系统，为了抵消信道失真，常在接收端用一个自适应逆滤波器进行处理，其传递函数等于信道传递函数的倒数。
系统辨识
所谓系统辨识，实质上是根据系统的输入和输出信号来估计或确定系统的特性以及系统的单位脉冲响应或传递函数。系统辨识的任务是根据输入信号和接收信号确定未知信道的特性。用自适应滤波器模拟未知系统，并通过调整其参数，使它在与未知系统具有相同激励时能够得到误差均方值最小的输出。自适应滤波器收敛后，其结构和参数不一定会与未知系统的结构和参数相同，但二者的输入，输出响应关系是拟合的或匹配的。
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
