udf的C源代码 fluent速度入口 速度函数为一个抛物线(C source code fluent udf velocity inlet velocity function is a parabola)

Divide/Create data into K-Folds training and testing data which are balanced basing on the labels. It is for k-fold cross validation.

关于matlab的讲座，matlab是一个很好用的工具，希望对大家有帮助。(lectures on Matlab, Matlab is a very good use of the tools, we hope to help.)

说明：  雷达信号去斜处理方法：去斜处理(宽带的匹配滤波)Stretch方法是针对线性调频信号而提出的, 其方法是将输入信号与参考信号 (经适当延迟的本振信号, 延迟量通常由窄带信号测距结果估计出) 混频(Radar signal de-obliquation processing method: The Stretch method of deskew processing (wideband matched filter) is proposed for linear frequency modulation signal. Its method is to mix the input signal with the reference signal (local oscillator signal with appropriate delay, the delay is usually estimated by narrowband signal ranging result))

说明：  傅里叶变换，FSERIES 返回傅里叶系列系数，代码中对参数有详尽的解释说明，方便看懂(Fourier transform, FSERIES back Fourier series coefficients, the code of the parameters detailed explanations, easy read)

说明：  simulink 通信仿真手册 里面详细介绍了每个模块的作用和详细参数设置(communication simulation simulink Manual which details the role of each module and detailed parameters set)

几个图象处理程序，用不同的方法进行图象重建(several image processing procedures, use different methods for image reconstruction)

QPSK调制全称Quadrature Phase Shift Keying ,意为正交相移键控，是一种数字调制方式。数字信号的四相相移键控调制与解调技术以其灵活性和通用性而得到广泛的应用，符合未来数字通信技术发展的方向。随着移动通信技术的发展，以前在数字通信系统中采用FSK、ASK、PSK等调制方式，逐渐被许多优秀的调制技术所替代。(QPSK modulation partial Quadrature Phase Shift Keying, Quadrature Phase Shift Keying means, is a digital modulation. Digital signal quadrature phase shift keying modulation and demodulation technology for its flexibility and versatility which has been widely used, in line with the future direction of development of digital communication technologies. With the development of mobile communication technology, previously used in digital communication systems FSK, ASK, PSK modulation, etc., many excellent modulation gradually being replaced by technology.)
