摘要
基于信号奇异谱分析思想，提出了奇异熵的概念，详细分析了信号信噪比与奇异 熵间的内在联系，并由此提出了一种在信号降噪过程中对信号奇异谱降噪阶次实现 合理定阶的新思想。
A new concept, singular entropy, is brought forward based on the thought of singular spectral analysis, from which, being enlightened by the relationship between signal/noise rate and the corresponding singular entropy, a dramatic idea for reasonably determining the noise reducing order of singular spectrum is presented.
