This Simulink model simulates as an example the transmission and reception of random digital data modulated with GMSK. The purpose of this model is to illustrate how part of the GSM transmission and reception works. It also measures the BER, affected by an AWGN channel.

说明：  BP神经网络异或问题 使用说明：打开文件夹中的BP.m文件，在matlab中运行此m文件，即可在command window中得出结果。压缩包内附说明文件 (XOR problem of the BP neural network for use: Open the folder in BP.m file, run this m file in matlab to the outcome of the command window. Compression package containing the documentation)

it s about equalizer and filter. The document is written in Indonesian and it s a report from the practical work

说明：  并网下垂控制仿真，单台并网逆变器，采用下垂控制(Simulation of grid-connected sag control, single grid-connected inverter, using sag control)

关于传染病的蔓延模型，包含潜伏期和隔离的完整模型(Model on the spread of infectious diseases, including incubation and isolation of the complete model)

线形调频信号带码调制,程序是自己写的 仿真效果也不错 环境是MATLAB(Linear FM signal with modulation code, the program is to write their own simulation results would be a good environment is a MATLAB)

这是doris的中文版本.学习起来,能更容易些,我认为.(This is the Chinese version of doris. To learn together, can be easier, I think.)

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)
