adaptive--filter--noise-

数字图像在产生过程中经常会受到噪音污染。因此，对于数字图像应该对其进行去噪音处理。在传统的基于傅里叶变换的信号去噪音方法中，可以使得信号和噪音的频带重叠部分尽可能的小，这样就可以在频域通过时，不需改变滤波方法而将信号和噪音分隔开来。但是，如果信号和噪音的频域重合时，用该方法进行噪音处理的效果就比较差。(digital image in the selection process will be subject to regular noise pollution. Therefore, the digital image should be carried out to deal with the noise. Based on the traditional Fourier Transform method of signal to noise, can result in a signal and noise bands overlap small as possible, so it can be adopted in the frequency domain, the need to change methods of filtering the signal and noise to separate. However, if the signal and noise in the frequency domain coincidence, the method for dealing with the effects of noise on the relatively poor.)

现代社会发展要求通信系统功能越来越强，性能越来越高，构成越来越复杂；另一方面，要求通信系统技术研究和产品开发缩短周期，降低成本，提高水平。这样尖锐对立的两个方面的要求，只有通过使用强大的计算机辅助分析设计技术和工具才能实现(Social development of modern communication systems require increasingly strong, the performance is getting higher and higher, which constitute more and more complex On the other hand, communications systems technology research and product development to shorten the cycle, reduce costs, improve the level. This in sharp opposition to the two requirements, only through the use of powerful computer-aided analysis and design techniques and tools can be achieved)
