随机信号AR频谱模型的本质研究

STUDY ON ESSENCE OF AR SPECTRUM MODEL FOR RANDOM SIGNAL

本文对期望为准周期函数的随机信号AR频谱模型进行了深入研究 ,将AR模型从平稳随机信号扩展到非平稳随机信号。研究了该AR模型的基本原理、成立条件、模型参数求解等问题 ,并利用该模型对一实际随机信号进行了频谱分析。

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.
