说明：  VBLAST 2发2收情况下的链路,可以实现误码率的计算 (STBC)

幅频键控ASK的相干调制解调以及非相干调制解调的仿真实现，源代码中作了详细的备注，通过学习该代码能够对ASK的调制解调有更加深入的认识(Coherent amplitude and frequency shift keying ASK modulation and demodulation, and non-coherent modulation and demodulation simulation, source code made detailed notes, by learning the code to the ASK modulation and demodulation of a more in-depth understanding of)

喷水推进器以及水面艇模型的建模与仿真,基于MATLAB的SIMULINK开发，源创代码(Waterjet and ship modeling simulation)

两个频率的凹口滤波对消干扰噪声，效果很好。希望大家仿真实验。(Two frequency notch filter to eliminate interference noise, the effect is very good. I hope everyone simulation experiments.)

首先扼要地阐述矩量法分析天线的一般概念和基本思想，然后分别采用几种不同的积 分方程对线天线进行矩量法分析，并与解析计算结果进行比较，两者的一致性说明了计算结果的正确性。(First, a brief moment method analysis of antennas described the general concepts and basic ideas, and then were used for several different line of antenna integral equation moment method analysis, and results were compared with the analytical calculation, the consistency between the description of the calculation accuracy of the results.)

主要用于计算目标前向、侧向、后向散射特征，同时完成RCS极坐标图的绘制(Used to calculate the target forward, sideways, backward scattering, and complete the drawing of the polar diagram RCS)

it is matlab m file

基于分数阶的傅里叶变换，很详细、具体，欢迎各位还下载(Based on fractional order of Fourier transformation)

平均误码率统计的的matlab程序，使用的时候还有一点注意事项，见程序内部说明(The average bit error rate statistics matlab program, when used, also Note, see the procedures for internal instructions)

采用四步相移方法求取相位主值，通过滤波对无效的像素点进行滤除。(With the four step phase shifting method to obtain the main phase, through the filter to filter out pixels invalid.)
