Abstract
Classical spectral estimation, whether the direct method or indirect method, are available to fast Fourier transform method, their concepts are clear and easy to understand, its resolution is proportional to . This paper describes the commonly used in modern power spectrum estimation based on AR model Burg algorithm, MATLAB simulation shows this method to estimate the power spectrum curve, results showed that the Burg algorithm in spectral resolution and model in the order of sub-option square than the self-correlation algorithm has obvious advantages.
