利用小波分解与重构,实现图像滤波和压缩,可灵活选用其他小波,简单易懂,特别适合小波初学者.(using wavelet decomposition and reconstruction, image filtering and compression, the flexibility to choose other wavelet is simple to understand and Wavelet particularly suitable for beginners.)

数字调制技术的发展日新月异现如今信息技术不断的推陈出新，信息的传输及通信起着支撑作用。而对于信息的传输，数字通信已经成为重要的手段。因此，数字信号的调制就显得非常重要。数字调制是通信系统中最为重要的环节之一，而实现数字调制需要的方法就需要用键控法来实现，比如可以对载波的振幅、频率和相位进行键控。(ASK , FSK , PSK modulation and demodulation of the simulation comparison )
