经典谱估计方法的MATLAB分析

Analyzing Classical Spectral Estimation by MATLAB

讨论了用MATLAB实现经典谱估计的各种方法 ,比较了它们的性能指标 ,并优选它们的参数 .得出了在科学研究和工程技术应用中有一定参考价值的结论 .

Although the methods for classical spectral estimation have some disadvantages, they still are used widely in the case of long data records by virtue of their conspicuous advantages of simple in computation and easy in implementation. Computation, visualization, and programming are integrated in a flexible and open software system environment in MATLAB. The various methods for classical spectral estimation are implemented by very simple m files on MATLAB, their performances are analyzed, the optimal choice of their parameters is discussed, and some results are obtained.
