| Abstract: | In practice,many mathematical expressions can not be derived from stationary signals,as there are some difficulties in getting the power spectral density of the signals.According to Wiener-Khintchine theorem,the paper suggested an estimation method for power spectral density of the signals based on Matlab programming.Simulation results show that the method is simple and comparatively accurate. |
