Estimation of model parameter for transient signal is very important in many aspects. This paper presents a new Markov ARMA model Q-slice estimation algorithm for transient signal based on bispectrum. Simulation results show that this new method has some special features, such as higher estimation precision, lower amount of calculation, higher fitting effect even in lower signal-to-noise ratio (SNR) situation. 展开更多

瞬态信号的模型参数估计在许多领域占据相当重要的地位。本文利用高阶矩的性质,提出一种Q-slice马尔可夫ARMA模型双谱估计算法。仿真结果表明,该方法估计精度高,计算量小,即使在低信噪比的情况下,对瞬态信号也有较好的拟合效果.
