| Abstract: | WT5BZ]The essence of AR spectrum model for random signal with quasi-cyclic expectation is studied profoundly.The application range of the AR model is extended from stationary random signal to unstationary random signal.The principle,the application condition and the method of identifying model parmeters are discussed in detail.The spectrum of a real random signal is analysed as an example at the end of the paper.
