SM系统matlab程序，传输天线、接收天线数量可调，信号调制方式可调，循环次数可调。最后生成BER性能曲线，并将不同SNR下的BER数据存储到mat文件中。(SM system matlab program, the number of transmission antennas, a receiving antenna is adjustable, adjustable signal modulation scheme, the number of cycles is adjustable. Last generate BER performance curve, and store data in different SNR BER under the mat file.)

说明：  控制外部程序 显示或隐藏 有需要的朋友可以下载试试 功能可以实现(控制外部程序 显示或隐藏)

根据给定的每15min预测一次的负荷数据，利用灰色预测GM（1,1）理论进行预测，并分别预测一周内周末和工作日的负荷变化情况，最终形成负荷变化曲线(According to the given load once every 15min forecast data, the gray prediction GM (1,1) theory to predict, and are predicted load changes within a week on weekends and weekdays, eventually forming the load curve)

BER Performance of Variable Width Sinc PAM with a Simple Receiver in AWGN

本程序实现2维TM波FDTD仿真 此程序用PML设置吸收边界条件 FDTD_2D_PML 仅含有Ez,Hx,Hy分量 (The procedure to achieve 2-D TM wave FDTD simulation of this process with the PML absorbing boundary condition FDTD_2D_PML set contains only Ez, Hx, Hy component)

三维空间离散点的曲面拟合,以及散点图做法(Three-dimensional surface fitting discrete points, and scatter plots practice)

matalb微分方程的解法，对于数理方程的学习和数学建模有参考价值。(matalb Differential Equation, for the study of mathematical equations and mathematical modeling of a reference value.)

matlab解常微分方程的一个非常好的PPT，可以让初学者尽快了解常微分方程的解法(matlab solution of ordinary differential equations of a very good PPT, so that beginners can understand as soon as possible the solution of ordinary differential equations)

混沌优化算法仿真实例，logistic映射产生混沌序列，求取函数极值。(Chaos optimization algorithm simulation example, logistic map chaotic sequence to strike function extremum.)

说明：  bpsk仿真中间有两个方面的内容，很好的仿真软件(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. )
