This paper proposes a new method of the FTS analysis and develops its parameter evaluation and model order estimation.
本文提出FTS分析的新方法，并研究它的参数估计和模型定阶。
However, the parameter model based PSD estimation is used with the assumption that the model order is determined as low as possible through prior knowledge.
而功率谱估计中基于参数模型的方法得到广泛应用，但建模时通常只能根据经验选择一个固定较低的阶数。
The estimation of the parameters can be easily done through EM algorithm and the order model is also easily selected by BIC criterion.
