摘要
自适应旋转投影分解法即AOP方法是一种新的时一频分析方法，它具有分辨率高、数据量少、无交叉干扰等优点．AOP分解所用的基函数是和语音信号的特征相符的．将AOP方法应用于语音信号处理技术中．无论是直接对时一频图的分析还是利用分解参数进行特征描述，都取得了令人满意的结果．此方法有着广泛的应用前景。
AOP is anew method of Time-Frequency Analysis which has high resolution , least dataout and has no crossterms . The basis functions used in AOP highly match speech signals . We decompose the speech signals with AOP into a sum of modulated Gauss functions. The result is used in speech analysis such as to get the basic harmonics. Experiments prove that the method presented is exellent.
