四节点等参元的matlab程序，可用于平面单元的有限元计算(four_node_quadrilateral_isoparametric_element matlabcode)

matlab GUI的设计说明，希望大家好好看看。(matlab GUI design statement, I hope you have a good look.)

是关于QPSK的一篇文章,对研究QPSK很有帮助的(Is an article on the QPSK, QPSK useful for research)

c# GUI+ 多种仪表盘，很难找的仪表盘，也很实用(c# GUI+ variety of dashboard, it is difficult to find the instrument panel, but also very practical)

逆变电路，matlab simulink 仿真，适合新手入门电力电子器件仿真(Inverter circuit, matlab Simulink simulation, suitable for novice power electronic device simulation)

说明：  对比了dv-hop基本算法，和加入pso后得算法。由于结果是随机产生的，不能保证每次得结构都能提高，但大部分时候，比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)

RNN预测(RNN_LSTM)

画图瑞利背景下CA CFAR检测性能比较的Matlab程序 (plot a figure speed platform where both the target and the clutter have range walk. In this method, for efficient clutter suppression the clutter’s range walk)

北斗二代卫星中37种伪随机码的产生程序代码，可选择几号卫星，生成4ms的伪随机码。(Beidou second generation satellite 37 kinds of pseudo-random code generation program code, you can choose a few satellites, generate 4ms pseudo-random code.)

实现信号的随机共振处理,包括matlab代码的实现(introduce the procedding of signal)
