基于Creator 大地景建模的研究与实现以飞行模拟仿真为应用背景,研究基于Creator 软件平台的大地景建模关键技术(research the key technology of large landscape modeling basing on Creato)

a matlab .m file describing a function acts as high pass filtr on an image

利用moravec算子提取特征点，非常经典，基本上其他的一些特征点提取算子是在它的基础上被开发出来的(Feature extraction using moravec point operator, very classic, basically some other feature extraction operator is based on it being developed by)

利用Kaiser窗设计一个低通滤波器，通带参数、阻带参数、阻带衰减、通带纹波都可以进行调整。程序简单易懂，按照凯塞窗设计滤波器的步骤，非常容易理解，得到的参数可以在MATLAB命令窗口中看到。(Kaiser window design using a low-pass filter, pass parameters, the stopband parameters, stopband attenuation, passband ripple can be adjusted)

通过simulink控制并仿真小车，实现避障(By simulink control and simulation car, realize obstacle avoidance)

说明：  Matlab中一种图像变声音的简单演示程序源代码。(Matlab image becomes a voice of a simple demonstration program source code.)

说明：  圆拟合，通过已知的多组数据，拟合出最小误差的圆(Given a set of measured x,y pairs that a re supposed to reside on a circle, but with some added noise. A circle to these points, i.e. find xc,yc,R, such that (x-xc)^2+(y-yc)^2=R^2)

DTMB，全称Digital Television Terrestrial Multimedia Broadcasting。上述资料包含了最新标准，及链路级仿真matlab代码(Digital Television Terrestrial Multimedia Broadcasting)

仿真4-PAM（脉冲幅度调制）载波调制信号在AWGN（加性高斯白噪声AWGN(Additive White Gaussian Noise)）信道下的误码率和误比特率性能，并与理论值相比较。(Simulation 4-PAM (pulse amplitude modulation) modulation signal in AWGN (additive white Gaussian noise AWGN (Additive White Gaussian Noise)) under the channel bit error rate and bit error rate performance, and compared with the theoretical value.)
