一种提高周期信号检测精度的自适应算法

An Adaptive Arithmetic for Reducing Spectrum Leakage

提出一种既能提高周期信号的检测精度 ,又不增加计算量的自适应算法 .该算法能自动调整采样得到的离散序列 ,使其最大限度地逼近理想离散序列 ,减少频谱泄漏 。

The paper gives an arithmetic that improves test precision of periodic signal as well as reduces calculational times.The arithmetic will adjust the discrete series that be gained by sampling,and makes it approach the ideal discrete series.The result of arithmetic processing shows that spectrum leakage is reduced evidently.
