Abstract :
A generalization of the multitaper spectral estimator is formulated and is shown to be equivalent to a generalized two-dimensional window, which allows a setting for non-stationary spectral estimation. The stationary case is specified as its restriction to a line in the two dimensional frequency plane. The formulation brings new tapers into consideration, and two of them are proposed and compared to the commonly used Slepian and sine-tapers.
