This paper describes a new spectral estimator based on the Fourier transform, the autocoherent spectrum (ACS), which enables the extraction of the pure sinusoidal components with a greater sensitivity and an improved frequency resolution. It's statistical properties are studied, and it is shown how
Spectral analysis is an important method by which the variation in a data set can be decomposed into waves of different frequencies. In the form of the power spectral density it is usually estimated directly from the data using the fast Fourier transform which often requires considerable pre-process
