| Abstract: | The modern spectrum estimation methods overcome the disadvantages of traditional spectrum estimation methods such as the large variance and low resolution. The power spectrum estimation of parameter model is the important content of modern spectrum estimation methods. This paper introduces the parameter estimation models of several common power spectrums, and com- pares the performance of the models through the simulation example,analyzes and discusses the selection of model step, which has definite reference value for the actual engineering application. |
