通过MATLAB来实现天线的一维，二维，三维的方向图，十分方便使用(MATLAB to implement the antenna by one-dimensional, two-dimensional, three-dimensional pattern, very easy to use )

In this paper, we propose and investigate a lowcomplexity human motion tracking system which is based on ultra-wideband (UWB) radio nodes.

雷克子波的matlab程序，地震勘探的很基础的子波(ricker wavelet)

1、观察采样引起的混叠。 2、判别离散时间系统的时不变性。 3、利用卷积计算信号通过FIR滤波器的输出，并观察输出信号的input-on暂态、input-off暂态和稳态阶段。 (One to observe the sampling due to aliasing. 2, determine the time invariant discrete-time systems. 3, the use of convolution calculation of the signal through the FIR filter output, and observe the output signal of the input-on transient, input-off transient and steady-state phase.)

说明：  一个和数据库连接的差别矩阵matlab源代码，自己编写的，有需要的可以看看。(And the difference between a database connection matrix matlab source code, I have written, and there is a need that can take a look at.)

SURF_DETECTOR SURF (Speeded Up Robust Feature) is a robust image detector and descriptor, first presented by Herbert Bay et al. in 2006, that can be used in computer vision tasks like object recognition or 3D reconstruction. It is partly inspired by the SIFT descriptor.

本程序实现2006年由Morelli提出的lear all(This program realization of 2006 by the proposed Morelli Lear all)

8PSK 调制，AWGN信道下的信道容量的matlab 仿真程序。(8PSK modulation, channel capacity under AWGN channel matlab simulation program.)

匀速直线运动和匀加速直线运动下的航迹生成方法、航迹测量方法、五点建航方法，亲自调试能能比较有效的建立航路(Uniform motion and uniformly accelerated linear motion trajectory generation method, track measurements, five-point method built aircraft, personally commissioning can build more effective route)

利用Matlab的模糊逻辑工具箱实现模糊控制系统仿真(Using Matlab' s fuzzy logic toolbox of Fuzzy Control System)
