本例很好的解释了FFT变换的功能，例程简单易懂，能够很好的用于理解FFT，观察信号频谱。(In this case a good explanation of the function of FFT transform routines easy to understand, can be very good for understanding the FFT, observe the signal spectrum.)

频谱细化分析的程序，程序包括着逐渐完成的几个过程程序，注意频谱细化是针对开始对象时连续的。(Detailed analysis of the spectrum, the program includes a process of gradual completion of several procedures, attention to refine the spectrum when the object is for consecutive starts.)

求一个信号的频谱分布，并求某一帧的频谱图。(Seeking a signal of the spectrum distribution, and the frequency spectrum diagram of the requirements of a certain frame.)

Alternative good LDPC codes for DVB-S2(In our following paper, we find that the shortten codes of DVB-S2 have some problems,this program can provide a good DVB-S2 LDPC code without cascaded BCH codes.

本文提出了基于二维混沌映射的数字图像水印算法，混沌具有随机性、似噪声及对初始条件的极端敏感性等特点。将经过二维混沌映射置乱后的数字水印信号嵌入图像小波域的低频系数，实现了数字水印的隐蔽性、保密性和稳固性；利用二维混沌映射Arnold变换对水印信号进行置乱，不仅增强了水印信号保密性，同时有效提高了视觉上抵抗图像剪切攻击的能力(failed to translate)
