| Abstract: | This paper deals with a new method for estimating the covariance functions and spectral density of real stationary normal sequence , and presents some sufficient conditions for asymptotically unbiased and weak consistent estimate. Under these conditions,the new method is obviously better than the cycle chart plus window estimate method in common use. |
