摘要
分析各种周期信号在直方图上的规律,提出一种等间隔序列方法来分选复杂周期信号,利用等间隔序列比原序列含有更丰富的周期信息,减小了直方图方法在复杂信号环境中判别信号周期的级数和复杂性,从而提高了分选"周期性信号"的速度。
Based on the analysis of the rule of each type of the signal in the interval histogram,this paper proposes a new method that using the series signals with the equal interval separates the complex periodic signals,which has more rich periodic information than primary series.It extremely reduce the progression and complexity of the histogram which is used to distinguish the periodic signal in complex surroundings.So,the rate of speed of the separation of complex periodic signals is improved extremely.
