  1. Studies have been made on arithmetic realization of apsd estimate in a high - speed detect system, since the way of calculating cpsd is only a little different from that of calculating apsd

    鑒于互功率譜密度估計演算法只需將功率譜密度估計演算法中的自協方差函數換成互,本文僅研究和討論了功率譜密度估計演算法及其實現。
  2. It comes up with a new notion, d - solution, which is applied to the distance estimation, by virtue of hilbert space ; furthermore, the dissertation has gained a necessary condition which is identity of minimum mean - square value in linear function classes, so that d - solution extends minimum mean - square value within the domain of nonlinear function equation or equation system ; and, the dissertation studies in detail the classical moment estimation and maximal likelihood estimation on the parameters of ar ( p ), a series of theorems in the estimation section shows the moment estimators are consistent on the ground of large samples jikewise, those distribution functions of the estimated parameters accord to maximum likelihood estimation converge gauss distribution if the white noise is gaussan

    首先,藉助hilbert空間理論,提出了距離估計的d -解,給出了d -解的必要條件,這個條件在線性類里即是極小二乘估計法, d -解的必要條件滿足的程實質上將極小二乘估計法推廣到多及非線性類。再而,詳細地研究了多元弱平穩序列回歸模型ar ( p )的參經典的矩的替代估計和極大似然估計,獲得矩的替代估計的一致性的結果。對基於gauss白噪聲假設多元弱平穩序列回歸模型的均值、白噪聲的陣的極大似然估計都有依分佈收斂到多元正態分佈的統計性質。
