基于simulink的码分多址扩频通信系统的仿真平台(DSSS-CDMA simulink)

在做毕业设计时编写的程序，主要内容是高铁环境下LTE系统的切换算法研究，源码中含scm信道模型。(a simulation about handover in LTE under high-speed railway station environment, which involving scm channel model.)

计算图像的各个指标，很有用，希望大家喜欢，谢谢(Calculated images of the various indicators, very useful, I hope you like it, thank you)

PID是控制中最为常用的算法，本程序包提供了PID参数设计模型，同时也提供了相应的具体实例。(PID is the most popular algorithm in control system, this package provides the modelling for PID parameter optimizing and the examples are presented as well.)

永磁同步电机数学模型，使用S函数编写，实验证明非常正确，请使用(Permanent magnet synchronous motor mathematical model, using the S function written in the experiment proved to be very correct, use the)

非线性方程组的求解在matlab中只有fsovle一个方法，其他方法还有很多(The solution of the nonlinear equations is only one method of fsovle in matlab, and there are many other methods.)

说明：  ldpc最小和译码算法，能够有效完成译码(LDPC minimum sum decoding algorithm can effectively complete decoding)

Matlab-瑞利波模拟程序，用于面波入射模拟(Matlab-Rayleigh wave simulation program for surface wave incident simulation)

这是瑞雷波正演模拟程序，时间2阶空间4阶，采用自由地表边界条件，可以直接运行。(This is the Swiss Leibo forward simulation program, the 2 order of time space 4, the use of free surface boundary conditions, you can directly run.)

说明：  用MATLAB对VSB 的调制解调进行仿真模拟，包括时域，频域，功率谱，加噪。(MATLAB to VSB modulation demodulation simulation, including time domain, frequency domain, power spectrum, add noise.)
