chi2test

平面桁架单元，力，长度，刚度，应力程序,使用matlab编制(plane truss force,length ,stiff,stress)

说明：  QPSK通过Rayleigh信道多径衰落的Matlab仿真 (无)

The MATLAB code which encrypt data based on AES technique.

用最小二乘支持向量机的算法做一个对正弦波信号的跟踪，跟踪效果很好(Using least squares support vector machine algorithm to make one pair of sine wave signal tracking, tracking works well)

一个chirp信号，用来描述连续震动的正弦函数。(A chirp signal, which is used to describe the sine function of continuous vibration.)

读取语音信号（用matlab的wavread指令），把语音信号分帧、加窗，进行清浊分割，提取基 频，这一部分较简单，自己编程序做。参考文献自己到图书馆期刊网上查找。 提取语音信号的lpc参数，可调用lpcfit.m 程序（我提供，见附件），将源、目标语音的浊音 段的lpc系数进行DTW规整，调用pathita2.m 程序（我提供，见附件）。将规整得到的lpc系数 转换成lsp参数，调用lpcar2ls.m 程序（我提供，见附件）， 再进行转换映射，调用matlab 的指令newrbe。(read the speech signal (using Matlab wavread Directive), Voice Signal frames, Windowed, Qingzhuo segmentation, extracting fundamental frequency, this part is relatively simple, they programmed to do. References their online journals to the library search. Voice Signal Extraction lpc parameters can be called lpcfit.m (I provide, see Annex), the source, Voiced objective voice of the lpc coefficient DTW structured, Call pathita2.m (I provide, see Annex). Structured to the lpc lsp conversion coefficient parameters, calling lpcar2ls.m (I offer see Annex), the shift mapping, called the directive newrbe Matlab.)

说明：  matlab编写的局部轨道不平顺，交点型轨道不平顺的（垂向，水平，方向，轨距不平顺）。(matlab prepared local irregularity, intersection type track irregularity (vertical, horizontal, direction, gauge irregularity).)

This is a matlab code for using no-overlapping windows of size WxW. It uses ind2sub and sub2ind() built in functions in matlab.

LT码编译码过程 BP译码 BER性能 高斯信道(LT coding-decoding process BP decoding BER performance of Gaussian channel)

都是测试程序，也就是模型，比如电机，磁链模型，很实用(matlab)
