NICAM

数字滤波器的各种结构的C程序实现，包含格型滤波器。本文没有讨论复杂的数学方法及公式。相信对正在为滤波器结构实现烦恼的人有所帮助。(Various structures of digital filter C program, including lattice filter. This article does not discuss the complex mathematical methods and formulas. I believe the troubles are achieving for the filter structure of human help.)

This source code describes the OFDM transmitted waveform at the transmitter both in frequency as well as time domain

Rotation Invariance using Fourier Mellin transform

读入COMSOL软件所生成的二维mphtxt三角形网格文件，读入相关网格的节点、三角形单元，边界信息。调用此函数时应将包含相关的路径与文件名的字符串作为输入参数。包 中包含了一个m函数文件与一个示例网格数据文件。 (read the information of 2-d triangle mesh file--*.mphtxt generated by COMSOL. The input parameter is the path and name of mesh file. A matlab source file and mesh file is included in it.)

说明：  自己做的两相混合式步进电机细分驱动控制，已经闭环成功，效果还不错(Self-made two-phase hybrid stepping motor subdivision drive control, has been closed-loop success, the effect is good.)

本实验先利用Mathematica求解非线性方程(组),探索不动点的性质 再利用MATLAB探索Koch分形的性质.(In this study, the first use of Mathematica for solving nonlinear equations (group), to explore the nature of the fixed point re-use of MATLAB to explore the nature of the Koch fractal.)

使用傅里叶变换提取心电信号中的呼吸信号，已经调试通过(Fourier transform to extract the breathing signal ECG has been through debugging)

turbo码的MAP解码 SISO_MAP_decoding(Single input single output MAP decoding)

说明：  MATLAB-数据处理-一个文件数据处理小程序(MATLAB-data processing-a small data-processing document procedures)
