摘要
Abstract
To better the resolution, this paper introduces the Burg spectrum estimate method into the frequency calculating of CMF without assuming the data out of data window. Resolution of Burg algorithm is affected by primary phase and noise. This paper improves Burg algorithm and introduces self - correlation to restrain the effect of primary phase and noise. The paper established the signal model of CMF,and carried out Matlab simulation. Simulation result showed that the precision of this algorithm is better than common requirement of CMF, and is not effected by sample frequency. This algorithm can be used in frequency calculating of CMF.关键词
