- Based on wavelet analysis , wls is the best linear unbiased estimator of regression model parameters in the context of l / f noise
基于小波技术的wls法是具有1 f噪声的系统回归模型参数的最佳线性无偏估计。 - A new method of the application of wls improved by r / s analysis to the monitoring of gas - solid fluidized bed is proposed
将改进的基于wls的ar模型法应用于气固流化床的流型辨识，提出了一种气固流化床过程监控的新方法。 - A method , called r / s analysis , is employed to improve the estimate accuracy of the hurst exponent . the simulation results show the method mentioned above is also an efficient filter
针对hurst指数的估计误差较大的问题，本文引入r s分析法，仿真研究表明该方法在提高hurst指数估计精度的同时提高了wls法的滤波效果。 - The main works as the following : r / s analysis is introduced to improve wavelet - generalized least squares ( wls ) in order to increase the estimate accuracy of the hurst exponent
本文的主要工作和创新点如下：提出了一种针对wls ( wavelet - generalizedleastsquares )的ar模型法的改进算法。引入r s分析法对wls法进行改进，以提高hurst指数估计精度及滤波效果。 - Experimental results show that wls is better than classical autoregressive ( ar ) models for 0 . 5 < h < 1 . it also can be seen that the disadvantage of wls is most salient for the lower of estimate accuracy of hurst exponent
本文对wls法进行了仿真研究，研究结果表明wls法对h 0 . 5的1 f噪声的滤除作用明显优于传统的ar模型，但同时发现wls法对hurst指数的估计误差较大。
