调试成功的循环前缀的最大似然同步算法源程序

提出一种两阶段的奇异点检测方法。将指纹图像分块，求出各块的方向构成块方向图，并在块方向图的基础上利用邻域方向的分 布分析结合改进的Poincare Index方法来确定奇异点所在的候选区域，对候选区域中的像素再通过计算局部方向变化率来确定奇异点的精 确位置。将此方法用于对FVC2004 DB1_A指纹数据库的图像，实验结果表明这种方法对指纹图像中的噪声有很好的鲁棒性，并且计算简 单快速，易于实现。 (A two-phase singularity detection. Fingerprint image block, calculate the direction of each block constitute a block pattern, and pattern in the block based on the use of the distribution of the direction of the neighborhood together with the improved Poincare Index method to determine the singular point where the candidate regions of the candidate region of pixels re-calculated to determine the rate of change of local direction of the precise location of singular points. This method is used to FVC2004 DB1_A fingerprint database of images, experiments show that this method of noise on the fingerprint image has good robustness and computing simple and fast, easy to implement.)

通过利用matlab设计仿真实验实现语音降噪 (Simulation by using matlab voice noise reduction design)

基于倒谱短时部分反映了语音的声道特性，先用汉明窗取一帧语音，然后经变换得到语音倒谱，将倒谱短时部分取出，进行正交反变换后将得到声道的对数谱，即得到语音频谱的包络。将频谱包络和频谱画在一张图上，有很好的对比效果。获取的包络效果十分好。(Based Cepstral partly reflects the short channel characteristics of the speech, first take a Hamming window with a frame of speech, and speech cepstrum obtained by converting the cepstrum short segment out inverse orthogonal transform to obtain channel will of the spectrum, i.e. to obtain the envelope of the speech spectrum. The spectral envelope and spectral painted on a chart, there is a good contrast. Get the envelope effect is very good.)

压控振荡器的压控算法控制，这个MATLAB仿真压控的PID算法，很有学习应用价值，是平常使用的，一定可行。 (VCO VCO control algorithm, the MATLAB simulation voltage control PID algorithm, great learning value is usually used, necessarily feasible.)

在登录界面中输入用户名与密码，输入正确之后，由界面生成的m文件直接调用视频导入界面，如果输入的用户名或密码不正确，那么系统将会提示输入的用户名或密码不正确，用户注册按钮则是将新的用户信息保存在information.xls文件中，当注册成功后，用户可以在下次登录时使用这个新的用户信息。
