Simulation of Power Spectrum Estimation based on AR Model

This article uses the principle of parameter model spectrum estimation, introduces the Burg algorithm in AR spectrum estimation, and gives the parameter estimation process of the Burg algorithm. Aiming at the procedural samples of the AR model, the Burg algorithm is used to estimate the power spectrum, and it is compared with the period map estimation method. The simulation results show that the power spectrum estimated by the Burg algorithm is close to the real power spectrum and is better than the result of the periodogram estimation method.
