Parameter Estimation in Diagonalizable Stochastic Hyperbolic Equations

W. Liu, S. V. Lototsky

摘要:

研究了加性时空高斯白噪声驱动下线性随机双曲型方程的参数估计问题。允许阻尼/放大算子是无界的。该估计器是谱型的,并利用有限数量的空间傅里叶系数的解决方案。在观测时间和噪声强度一定的情况下,研究了估计量随傅里叶系数增加的渐近性质。

英文摘要:

A parameter estimation problem is considered for a linear stochastic hyperbolic equation driven by additive space-time Gaussian white noise. The damping/amplification operator is allowed to be unbounded. The estimator is of spectral type and utilizes a finite number of the spatial Fourier coefficients of the solution. The asymptotic properties of the estimator are studied as the number of the Fourier coefficients increases, while the observation time and the noise intensity are fixed.
