摘要
通过对小波变换的基本小波的性质进行研究 ,构造出一类新的基本小波 (作者把它称为余弦调频小波 ) ,论证了其作为基本小波的必要条件并讨论了它的性质。并结合信号分析进一步说明了其实用性。
Based on the character of the basic wavelet, a sort of basic wavelet functions named as frequency modulation cosine wavelet is constructed, which satisfies with the necessary condition as basic wavelet. The characters of frequency modulation cosine wavelet are discussed, and its practicability and effectiveness are verified by analyzing communication signals.
