摘要
为了把描述过程信号的三种方法:AR谱估计法、prony方法、pisarenko方法归纳在一个理论模型下.通过对指数函数型复数过程信号的建模研究,得出了一个统一的方程组,即统一的AR模型.由该模型出发,经过预测分析、无衰减正弦过程参数估计和定价讨论后可知:在不同的条件下,此理论模型可分别导出AR谱估计法,无衰减信号的prony谱估计方法和pisarenko方法.
AR spectrum estimation method, prony method, pisarenko method were united into a general theoretical model. After studying the modeling procedure of exponential complex signals, an unified set of equations, namely unified AR model was derived in this paper. Under different conditions, AR spectrum estimation method, prony method, Hildebrand's prony spectrum estimation method, and pisarenko method can be led respectively by this theoretical model, after forecasting analysis, parameters estimating of no attenuation sin process signal and ordering discussion.
