三类目标的散射点模型，分别建立模型，并且画图，三个文件代表三类对象(Three types of target scattering point model)

Linear control systems

分析带通采样定理的原理和实现过程，说明带通信号重构原始信号的方法，仿真给出不同采样频率和低通采样性能对比(By analyzing the principle and implementation process of the bandpass sampling theorem, the method of reconstructing the original signal with the signal is explained, and the performance comparison of different sampling frequency and low pass sampling is given.)

在DCT域，利用8*8分块DM方法，嵌入隐藏信息。可设置量化步长、选择各种经典的攻击方式和控制攻击强弱。返回误码率和峰值信噪比。利用Matlab编写。(In the DCT domain, the use of 8* 8 block DM methods, embedding hidden information. Quantization step size can be set to choose a variety of classic attacks and control the strength of the attack. Return to the bit error rate and peak signal to noise ratio. Prepared using Matlab.)

LAMDA方法，进行模糊度解算前降低相关性处理(LAMDA for decorrelation of ambiguity resolution)

通过ｂｉｄ　，ａｓｋ的分布，用以计算当前市场的交易活跃程度。可以分别统计出卖方触发单和买方触发单(Through the distribution of the bid, ask, for the current market trading activity. Respectively statistics triggered single and buyer seller trigger single)

粒子群算法优化多峰函数，对初学者而言是很有帮助的一个东东，希望大家能够喜欢(Particle swarm optimization multimodal function, it is helpful for a beginner stuff, hope you will enjoy)

PSO optimization exa

minimum mean square estimator log spectral amplitude is an anhanced technique of the minimum mean square estimator developed by Ephraih and Malah in 1985.It is used for signal processing by improving the Signal to noise Ratio.
