说明：  本书是研究生数字信号处理提高课的教材。全书共13章，涵盖了“现代信号处理”中时频分析、滤波器组及小波变换这三大知识体系。编写中，力求注重理论和应用相结合，力求有利于数学和读者的自学，力求较为全面地反映这三个知识体系的主要内容。本书附光盘一张，包括了100余个用MATLAB6.5编写的程序和一些数据文件。这些程序概括了书中所涉及的绝大部分例题和插图，运行这些程序即可重现这些例题的结果和相应的插图，有利于帮助读者理解书中较为复杂的理论内容。
(the book was a graduate of digital signal processing to improve the teaching lesson. The book has 13 chapters, covering "modern signal processing" time-frequency analysis, filters and wavelet transform these three knowledge systems. In preparation, sought to focus on theory and application integration, seeks to mathematics and the readers to learn, to seek to reflect a more comprehensive system of knowledge that the three main elements. The book : a CD-ROM, including more than 100 Matlab6.5 prepared with the procedures and some data files. A summary of these procedures involved in the book most of the examples and illustrations, run these procedures can be retained these examples of the results and the corresponding illustrations, will help readers understand the book more comple)
