本文重新构造了一种最小二乘通道格形滤波器，并将它用于同时辨识ＡＲＭＡ模型的参数和阶次．数值仿真结果表明，这种辨识算法具有计算量小、精度高等优点
This article reconstructs a least-squares channel trellis filter and uses it to simultaneously identify the parameters and orders of the ARMA model. Numerical simulation results show that this identification algorithm has the advantages of low computational complexity and high accuracy
