这是国标数字电视地面传输标准里信道编解码器的MATLAB程序，用的是LLR-BP的解码算法，请大家指正。另有根据国标生成的生成矩阵和校验矩阵稍后传上来(This is the national standard of digital TV terrestrial transmission standard in channel codec MATLAB program, using the LLR-BP decoding algorithm, please correct me. Otherwise in accordance with GB-generated matrix and calibration matrix generation later Chuan-up)

包括手写文字识别的各个步骤，图像的预处理、裁剪、大小转换、人工神经网络训练和识别等等。(Handwritten character recognition, including the various steps, image preprocessing, cropping, size, conversion, training and recognition of artificial neural networks and so on.)

均匀线阵的MUSIC算法MATLAB仿真 需要的下载共享哦(ULA MATLAB simulation of the MUSIC algorithm needs to download shared Oh)

常规PID与模糊PID的比较，模糊调节的速度更快。(Comparison between conventional PID and fuzzy PID)

LDA降维是常用的降维手段之一，其本质假设为数据的高斯分布。是有效常用的有监督学习降维工具。(LDA dimension reduction is one of the commonly used dimensionality reduction methods, and its essence is assumed to be the Gauss distribution of data. It is an effective and commonly supervised learning dimensionality reduction tool.)

根据已给ecg数据文件，画出心电图波形，并自动标记出特征点位置，并计算P-R时间间隔 等参数。 附件是.dat为数据文件，为二进制文件，每2个字节代表一个采样点，采样频率1000hz。依 次为1-12导联的第一个采样点，其次是1-12导联第二个采样点，.... .hea头文件是文本格式说明文件，可以看到十二导联存放的先后顺序。 (According to the data file has to ecg, draw the ECG waveform, and automatically mark the feature points, and calculate parameters such as PR interval. The attachment is. Dat for data files, binary files, each 2 bytes represent a sampling point, the sampling frequency 1000hz. Followed by a 1-12 lead in the first sampling point, followed by 1-12 second sampling point lead ,..... Hea header file is a text file format that you can see the sequence)

基于Matlab-Simulink仿真的双闭环直流调速系统的设计与研究 如题,设计要求、设计公式及计算过程比较清晰,格式也是按照标准设置的,正文限于公式编辑的格式,排版不是太完美(Design and Research of Matlab-Simulink simulation of double-loop DC speed control system, such as the title, design requirements, design formulas and calculation process is relatively clear, but also in accordance with the standards set by the format, text format is limited to a formula editing, typesetting is not perfect)
