摘要
通过实验八种经典和现代的数字信号谱估计算法,并分析了这几种谱估计算法对不同特性信号主要包括周期信号、声音信号和随机信号的影响和差异,从这些算法所表现出的特征和差异中得出针对不同特征信号的谱估计算法性能的优劣性。
By accomplishing eight classical and modern digital signal spectrum estimation algorithms, this paper analyzed the effects and differences caused by these spectrum estimation algorithms among different signals including periodic signal, acoustical signal and random signal. From the attributes and differences represented by these algorithms we get the advantages and disadvantages of different spectrum estimation algorithms used to analyze different character signals.
