基于掌纹识别的在线身份验证 识别算法本科毕设，包含了阵列信号处理的常见算法，Gabor小波变换与PCA的人脸识别代码。( Verify recognition algorithm based on palmprint recognition undergraduate complete set of online identity, Contains a common array signal processing algorithm, Gabor wavelet transform and PCA face recognition code.)

Welch法：Welch法对Bartlett法进行了两方面的修正：一是选择适当的窗函数w(n)，并在周期图计算前直接加进去，加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时,可使各段之间有重叠，这样会使方差减小。(Welch method: Welch method of Bartlett method amendments in two respects: First, select the appropriate window function w (n), and in the cycle before CALPHAD directly incorporated, plus the advantage of the window, no matter what kind of window function can be so spectral estimation of non-negative. Second, when in subparagraph can overlap between paragraphs, this would reduce the variance.)

channel modulation and detection

PFUKFEKF三种滤波算法的对比比较，有图(The PF UKF is the EKF comparison of the three filtering algorithm, Fig.)

瑞利信道的仿真程序qpsk还有ber，snr仿真图形(Qpsk Rayleigh channel simulation program there ber, snr simulation graphics)

该源代码为迭代控制源代码，自己辛苦编的，拿来分享(The source code to the the iterative control source code, their hard work, and for them and share)

分别采用滞环电流和电压空间矢量技术进行PWM调制,波形完美(Respectively using hysteresis current and voltage space vector PWM modulation)

说明：  T型三电平逆变器仿真，能够对初学者提高帮助(the simulation of T-type three-level inverters. Good stuff,)
