MATLAB编程书籍，是MATLAB中不错的书籍，也是初学MATLAB编程入门必备书籍(The the MATLAB programming books, good books MATLAB, beginner MATLAB programming entry required books)

利用Matlab软件编写的轨道不平顺数据分析程序能够对轨检车测得的不平顺数据进行处理,得到功率谱密度分布函数.轨道不平顺分析程序包括轨道不平顺数据预处理、轨道不平顺谱分布函数计算以及根据实测的车体振动加速度,对轨道不平顺与车体振动加速度进行相干分析、提出对行车运行有不利影响的不平顺波长范围等.研究结果表明:车辆的动力特性与轨道不平顺有密切关系.高低不平顺对车体垂向振动影响显著,轨向不平顺对车体水平振动影响显著,水平不平顺对列车垂向、横向振动均有显著影响.(Matlab software written track irregularity data analysis program able to track inspection car irregularity measured data are processed to obtain the power spectral density function. Track Irregularities track irregularity analysis procedures including data preprocessing, track irregularity spectrum distribution function calculations, and based on the measured vibration acceleration of the vehicle, with the body of track irregularity acceleration coherent analysis, have an adverse impact on traffic running irregularity wavelength range, etc. the results show that: the dynamic characteristics of the vehicle and the track irregularity closely related. rough along the vertical vibration of the vehicle significantly, rail irregularity vibration to levels significantly affect the body, the level of irregularity to train the vertical and horizontal vibration significantly affected.)

能实现局部线性嵌入算法来完成数据的降维，需要设置参数有K，d(To achieve local linear embedding algorithm to perform data dimensionality reduction, you need to set the parameters K, d)

基于MATLAB的OFDM系统设计，QPSK调制，加循环前缀，经过瑞丽多径信道，没有信道估计。

8PSK解调算法的实现，希望对进行调制解调的朋友有所帮助！(8PSK demodulation algorithm, want to be friends modem help!)
