The advanced FFT and PPP method are presented to decrease effect of noise on spectrum parameters,thus some satisfactory spectrum parameters are obtained under the condition of weaker signal and bigger spectrum width The experiment shows:the result is better than value gained by primary FFT and PPP method,and some conclusions are given nd discussed.
