具有时频双特性的信号分析算法

Duple Features of Time and Frequency Domain Algorithm of Signal Analysis

提出一个在时域和频域同时具有良好特性的信号分析算法,在从一个复杂信号中提取某个或某几个信号分量时,具有较高的应用价值,特别是在检测信号中的微弱瞬态成分时,该算法不仅能检测到微弱瞬态成分的存在,而且还能够精确地确定其发生的时间,其优越性是常规的频谱分析所不能比拟的.仿真实验证明,该算法是切实可行的.

A signal analysis algorithm in this paper is offered with good characteristics at the same time of the time and the frequency domain. It has the higher application value while extracting a certain or some few signal weights from a complex signal, especially, it not only can detect the existence of the faintly gleam signal, but also can make sure when it takes place, its superiority is bigger than the normal regulation spectrum analysis. The experiments show that using new algorithm can produce more satisfactory results.
