一种减少频谱泄漏的自适应算法
A Adaptive Algorithm for Reducing Spectrum Leakage
摘要
Abstract
A kind of algorithm that improves test-precision of periodic signal is proposed and the calculation time reduced. When the multiple of the period of periodic signal is equal to the product of the period and the number of sampling, the discrete series calculated by the algorithm is equal to that gained by sampling directly.When the multiple of the period of periodic signal is not equal to the product of the period and the number of sampling, the algorithm will adjust the discrete series gained by sampling, and make it approach the ideal discrete series. The result of the algorithmic processing shows that the spectrum leakage is reduced.关键词
