64QAM 基于MATLAB调制解调仿真，部分(64QAM)

集合dsb调制与解调完整程序，很辛苦找到的(A complete set of FSK modulation and demodulation process, it is hard to find)

仿真对象如下： 其中， v( k )为服从N (0,1) 分布的白噪声。输入信号u ( k) 采用M 序列，幅度为 1。M 序列由 9 级移位寄存器产生，x(i)=x(i-4)⊕x(i-9)。 选择如下辨识模型： 加权阵取Λ = I。 衰减因子β = 0.98，数据长度 L = 402。 辨识结果与理论值比较，基本相同。辨识结果可信 (he simulation object is as follows: among them, v (k) to obey N (0, 1) distribution of white noise. The input signal u (k) using M sequence, amplitude is 1. M sequence by 9 level shift register generation, x (I) = x (I- 4) ⊕ x (I- 9). Choose the identification model: weighted array take Λ = I. Attenuation factor β = 0.98, the data length L = 402. Identify the theoretical calculation and comparison, basically the same. Identification results are reliable)

250KV line simulation program

这是matlab simulink 编写的永磁同步电机的双闭环控制系统结构，可以仿真转速电流的双闭环控制(matlab simulink spwm PMSM)

说明：  喷泉码中LC码的仿真程序，平台是matlab，除了仿真程序外，还包括对喷泉码的简单介绍(The simulation program of LC code in fountain code is based on MATLAB. In addition to the simulation program, it also includes a brief introduction of fountain code)

运用matlab软件，编程运算，进行回归分析(Use matlab software, programming operations, the regression analysis)

各种分布之下的随机数matlab生成代码，共18种分布，比较全面，研究随机数常用代码(Matlab distributed under a variety of random numbers generated code, a total of 18 kinds of distribution, a more comprehensive study used a random number code)

this is about risk managment problems....
