Mathews, V. John | A unified approach to nonparametric spectrum estimation algorithms | Abstract-Different approaches to spectrum estimation can be broadly classified as parametric and nonparametric methods. In the parametric techniques, an underlying model is assumed in the formulation of the spectrum estimation problem and one estimates the parameters of the model. For nonparametric... | 1987 | |
