对轴承故障振动信号的matlab小波分析程序，能完成对故障特征频率的提取(Of bearing fault vibration signals matlab wavelet analysis procedures, can finish on the fault characteristic frequency extraction)

canny边缘检测算子,可以对灰度数字图象的弱边缘进行很好的检测(canny edge detection operator, Gray figures to be the weak image edge detection for good)

OFDM系统中提出一种改进方法对频偏的捕获, 在联合使用9个短前导序列和长前导序列估计算法的基础上,采用鉴频环路的方法来消除算法中的除法和取模运算 (OFDM system in an improved way of deviation of the capture, in the joint use of nine short leader sequence and the long preamble sequence estimation algorithm, based on the frequency discriminator method to eliminate the loop algorithm in the division and modulo operation)

混频信号通过低通滤波器后的信号的频谱图,matlab程序 有注释(Mixed signal through the low pass filter of the signal spectrum.)

wavelet,很好用的原码哦，一起试试吧(wavelet, with the original code Oh well, try it with)

用MATLAB实现fir滤波器，有窗函数法，切比雪夫法，以及最后用lattice结构实现出来

matlab bacpropagation neural network

HHT gcc代码，专门用于希尔伯特黄变换。(HHT gcc code, specifically for the Hilbert-Huang Transform.)

this code is used for processing all the directory

说明：  用DFT计算连续信号的谱 通过应用 DFT 进一步加深对离散信号 DTFT 和 DFT 的概念及其相互关 系的理解。 =利用 DFT 计算连续周期信号的频谱(DFT calculations using a continuous signal by applying the DFT spectrum of discrete signals to further deepen the concept of DTFT and DFT and their mutual understanding of the relationship. = DFT calculations using a continuous spectrum of periodic signals)
