QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

箱体右侧一块挡板以15m/s速度下滑，求解箱体内流函数‐涡量方程。取Δx=Δy=0.01m,Δt=0.001sec。 自己编写的Matlab代码。(Box the right side of a shutter speed of 15m/s decline solving the the cabinets stream function- vorticity equation. Taken Δx = Δy in = 0.01M, and Δt = of 0.001.)

Theory of PDH communication for programming in any language

说明：  这是一个用c++实现的程序，功能：熟悉Mallat 算法、Daubechies 小波的构造、样条小波的性质(err)

neural network coding for image classification

双基地MIMO雷达参数估计中，运用MUSIC算法估计目标的到达角度(Bistatic MIMO radar parameter estimation, the use of MUSIC algorithm to estimate the target s arrival angle)

求解线性矩阵不等式的程序，简单明了，有注释，对于学习LMI有很好的帮助(Procedures for solving linear matrix inequalities, simple and clear, with annotations, very good for learning with the help of LMI)

程序实现了C++和MATLAB的混合编程，对接的方法是使用Matcom组件。程序实现的功能是，绘制一个sin函数。(Program implements C++ and MATLAB mixed programming, docking method is to use Matcom components. Program' s function is to draw a sin function.)

说明：  偏最小二乘法中的交叉有效性计算的matlab程序，怎么计算出来的预测误差平方和PRESS不太对，偏大；()
