摘要
本文讨论了最大熵(熵的定义为H= -integral from n=1/2 to 1/2 s(f) logs(f) df)谱估计的误差来源,提出了两种减小谱估计误差的方法。计算机仿真验证了上述理论的正确.
In this paper, the origin of the spectral estimation errors in the manimum eutropy method wheve the definition of entvopy is H=-integral from n=(-1/2) to (1/2) s(f) Ins(f)df is first analyzed.Then,two approaches madifying the spectral estimation errors are presentedl. Finally, the relevant results of enperiments are given which check well with the thearetical anaeysis
