设定噪声为高斯白噪声，对2ASK、2FSK、2PSK、2DPSK等各种调制方式及相应的主要解调方式下（分相干与非相干）的误码率进行统计，并与理论值进行比较，以图形方式表示误码率与信噪比间的关系。(Set the noise is Gaussian white noise, right 2ASK, 2FSK, 2PSK, 2DPSK a variety of modulation and corresponding demodulation mode, the main (sub-coherent and non-coherent) and bit error rate statistics, and compared with the theoretical value , a graphical representation of the bit error rate and SNR relationships.)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

毕业设计时编写的MATLAB程序，实现的lCGuTi特征提取，并做在不同光照、不同视角下的特征匹配，最优guLZQyD差值计算方法，有应用matlab进行编程的源代码.m文件,以及运行需要的图象文件 (Upon graduation design written MATLAB program to achieve the lCGuTi image feature extraction, and do feature different light, different perspectives match under optimal guLZQyD difference calculation method, there are application programming source code matlab .m files and run picture file required. )

放大显示matlab输出图像局部区域，放大区域可以随意在原图像拖动，相应的放大区域会显示出来，同时显示放大区域和源图像。(Magnified display matlab output image local area, zoom in the region can be free to drag the original image, the corresponding amplification area will be displayed, while displaying the enlarged area and source image.)

这个程序主要是用来设计实现一个加解密的系统 采用matlab设计 用了二进制循环 异或的知识(与刚才对应的解密程序)(This program is mainly used to design and implement a system of encryption and decryption using matlab design cycle using the binary XOR of the knowledge (and have the corresponding decryption process))
