This folder has two files for the simulation of universal motor. please run the *.m file to run the *.mdl file(This folder has two files for the simulation of universal motor. please run the*.m file to run the*.mdl file)

OFDM信道估计程序 是基于导频的OFDM信号信道估计的matlab程序(OFDM channel estimation procedures is estimated based pilot OFDM signal channel matlab program)

the algorithm is about edge detector that is used to detect edges in an image. Prewitt , SobeL and Robertsfilters are used

例1 采用动量梯度下降算法训练 BP 网络。 例2 采用贝叶斯正则化算法提高 BP 网络的推广能力。在本例中，我们采用两种训练方法，即 L-M 优化算法（trainlm）和贝叶斯正则化算法（trainbr），用以训练 BP 网络，使其能够拟合某一附加有白噪声的正弦样本数据。(Example 1 uses the momentum gradient descent algorithm to train the BP network. Example 2 uses the Bayesian regularization algorithm to improve the generalization ability of BP network. In this example, we use two training methods, the LM optimization algorithm (trainlm) and the Bayesian regularization algorithm (trainbr), to train the BP network to fit a sine sample with white noise data. )

GSM的全速率语音编码，利用MATLAB仿真实现，规则激励长时预测分析，发送端提取语音信号特征，并用一定的二进制位数进行编码，接收端再根据编码还原成语音信号。包括编码和解码部分，采样8000赫兹，传输码率13kbps,模拟GSM系统，实现语音编码。

十种软件滤波.rar介绍了十种软件滤波的方法,不过我建议还是使用模拟滤波方法好.(10 kinds of filtering software. Rar introduction of dozens of software filtering method, but I suggest that the use of analog filtering methods or good.)

说明：  蓝牙调频通信系统，为simulink形式，直接运行可用(Bluetooth FM communication systems for the simulink form, can be used directly to run)
