说明：  一个4阶的切比雪夫Ⅰ型低通滤波器，可以用它对信号进行滤波。当然，滤波器的零极点图也是必不可少的。(A 4-order Chebyshev low-pass filter of type Ⅰ, you can use it to filter the signal. Of course, the filter pole-zero map is essential.)

通过matlab实现拉格朗日乘子法。学习经典优化方法，熟悉matlab语言。(Realize the Lagrangian multiplier method by matlab. Learning classic optimization methods, familiar with matlab language.)

声波传输损耗，有利于节约你的时间，希望广大爱好程序计算者喜欢 (acoustic transmission loss)

基于m序列的直接序列扩频系统的抗噪声性能仿真 (Anti-noise performance simulation based on direct sequence spread spectrum system m sequences)

sift算法的基础论文，很经典，还有一篇sift的讲解，由于上传限制，如果有需要可以向本人索取(sift algorithm based on papers, very classic, there is a sift in the talks, the upload limit, and if necessary I can be obtained)

通过锁相环的方法实现2fsk的传输系统的设计，，这是仿真图。。仅供参考(Achieved through the PLL 2fsk designed transmission system, which is the simulation of Fig. . For reference only.)

说明：  基于模拟退火的粒子群算法，基于自然选择的粒子群算法，基于杂交的粒子群算法(Based on simulated annealing particle swarm algorithm, based on natural selection, particle swarm optimization, particle swarm optimization based on hybrid)
