图像分类。将图像中的40个样本作为训练样本，训练得到分类器，将另外160个样本作为测试样本测试分类器的效果。(Image classification. The image of the 40 samples as training samples, the trained classifier, an additional 160 samples as a test sample test classification results.)

MATLAB 实现拉格朗日插值算法 (Lagrange interpolation algorithm in MATLAB)

可以通过输入刚度或阻尼数组，生成刚度（阻尼）矩阵。(The stiffness (damping) matrix can be generated by input stiffness or damping arrays.)

关于OSTBC的天线选择，采用天线选择的Alamouti STBC方案，比较BER性能，由仿真图能得出天线选择方法能够提供比预编码更多的增益。(About OSTBC antenna selection, antenna selection scheme using Alamouti STBC, compare the BER performance, can be reached by a simulation diagram antenna selection method can provide more than pre-coding gain.)

PV system working very good

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与 理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据。 (The introduction was done with the principle of the QPSK modulation and demodulation in digital communications，a script was written by using Matlab program to CalTy out a simulation of the QPSK communication system．which contains the concrete realization of transmit and receive process．The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise，spectral analysis of each module is also done，the results obtained with theoretical results in the main，which provides an effective frame of reference for understanding the performance of QPSK systems，and the practical application in the system to make further designed．)
