Script for computing the BER for BPSK modulation in a Rayleigh fading channel with selection diversity

this source code based on steganography and developed in matlab. in steganography we can hide any data like images in another image. this method based on discrite cosine transform method.

本程序用于仿真QPSK的解调(procedures for the simulation of the QPSK demodulator)

L曲线具有很多的优点，这是用MATLAB编写的病态方程的L曲线解决方法，可以通过L曲线确定所需的参数。(L curve has many advantages, it is written in MATLAB morbid equation L curve solution that will be needed through the L curve to determine the parameters.)

混沌现象出现于非线性系统中。Matlab模拟了复摆运动行为及混沌现象(Chaotic phenomena in nonlinear systems. Matlab simulation of the compound pendulum movement behavior and chaos phenomena)

PSCAD仿真实验内容实验4 避雷器 脉冲测试电路(PSCAD stimulation lightning arrester)

parabolic equation solver matlab code

matlab下filter程序，有脉冲响应法和双线性变换法生成filter，各参数有详细注释，有信号滤波前后的图形、频谱及相位对比。(Under filter matlab procedures, generate filter impulse response method and bilinear transformation method, various parameters are detailed notes, graphics, spectrum and phase contrast signal before and after filtering.)

说明：  利用自适应粒子群进行寻优，实验效果良好，其中具体参数要根据实际调节(Using adaptive particle swarm optimization, the experimental results are good, and the specific parameters should be adjusted according to the actual situation.)

计算大气折射修正，利用分段模型，采用matlab软件编程计算(matlab caculate the refraction of atmoshpere)
