beamforming

This is the customized programmable pulse generator using matlab

bpsk的调制与解调的过程，并采用卷积码，讨论其误码性能随着其功率、频偏、相偏而变化.(bpsk modulation and demodulation process and using convolutional codes, to discuss its error performance with its power, frequency offset, phase offset changes.)

小波包分析提取振动信号中的特征频率，计算十字叉丝的在不同距离的衍射图像,可直接计算得到多重分形谱。( Wavelet packet analysis to extract vibration signal characteristic frequency, Calculation crosshairs diffraction image at different distances, It can be directly calculated multi-fractal spectrum.)

在天然地震数据中提取频散曲线，研究面波的频散特性。有很好的效果。(Seismic data extracted natural dispersion curves, dispersion characteristics of surface waves. Have a good effect.)

在现代信号处理中对信号进行的多种加窗操作程序，如hamming窗，hanning窗(In modern signal processing of signals, plus multi-window operation, such as the Hamming window, hanning window)

完整的用sobel算子进行边缘检测的例子(Complete with a sobel edge detection operator is an example)

里面有三个二维模糊调节器分别实现PID控制器的参数Kp，ki，Kd，的调节。其控制原理：根据前面的偏差e和偏差变化ec将三个模糊控制器FC1,FC2,FC3分别进行模糊化，模糊逻辑推理，解模糊化。最后得到pid控制器参数调节量。(There are three-dimensional fuzzy regulator PID controller parameters Kp, ki Kd, adjust. The control principle: the front of the deviation e and error change ec three fuzzy controllers FC1 has FC2, FC3, fuzzification, fuzzy logic inference, defuzzification. Finally, get the pid controller parameter adjustment.)
