摘要
利用三阶累积量ＡＲＭＡ模型的特点及模型拟合的多样性，基于最小均方误差准则提出了估计模型阶次的算法，恢复衰减谐波信号的仿真实验表明该方法具有更好的信号重构性能。
By means of the third-order cumulant ARMA model and its multi-kinds of fitting property, an LSE-based algorithm to estimate the orders of the model is proposed, and the corresponding simulation experiments, in which the algorithm is used to reconstruct the harmonic signals, show that the proposed method has a higher accuracy.
