exercise_1

用前后向空间平滑法实现相干信源DOA估计(using the method of forward and backward spacial smoothing to realize coherent signal DOA)

CDT规约，统称循环式远动规约，电力调度系统经常使用，经多年实践验证通过，需要时，可修改自己内部接口，完成代码移植。(CDT Statute, collectively, cycle remote Statute, power dispatching systems often use, after years of practice verified, if necessary, to modify their own internal interface, complete the code transplant.)

说明：  通过simulink建立电磁阀模型，通过pwm控制，控制电磁阀的开闭(The model of solenoid valve is established by Simulink, and the opening and closing of solenoid valve are controlled by PWM control)

median feltering......median.m and median_filter.m

用MATLAB实现MPEG中的 ZIG-ZAG 扫描，矩阵查表实现，函数形式，很有用。(MPEG with a MATLAB implementation of the ZIG-ZAG scan matrix look-up table implementation, functional form, is useful.)

M-PSK Recovery for Modem Design.

说明：  免疫算法详细编程，有中文介绍，很好的资源。。。(Immune algorithm detailed programming, a Chinese introduction, a good resource. . .)
