On the High-Resolution of the Spectral Density Function of a Stationary Time Series

This paper is devoted to introducing and applying a powerful method in estimation of the spectral density function of a discrete time stationary time series, which is called the high-resolution estimation. The method of estimation is compared with some classical methods using a simulated example.
