Description: According to Wiener- Xinqin theorem, wide-sense stationary random process is the power spectrum of the autocorrelation function value. But for many practical applications, Keziliyong observational data are often limited, so to accurately calculate the power spectrum is usually not possible. A more reasonable goal is to try to come to a good power spectrum estimation, this is the power spectrum estimation. This paper analyzes the power spectrum estimation and modern classical power spectrum estimation of a variety of methods to compare the advantages and disadvantages of various methods.
