matlab的几种DTFT计算方法，M文件(matlab Several DTFT calculation method)

此程序以美国黄石国家公园为例，构造尽可能贴近实际的仿真环境，从而通过仿真得到野火发生频率与野火规模之间的数学模型。这是一个经典的幂率模型，稍作改造好即可模拟“28原则”、“网站点击率”等幂率相关问题。(This procedure to Yellowstone National Park as an example, the actual construction simulation environment as close as possible to the simulated wildfire through the frequency and size of wildfires between the mathematical model. This is a classic power law model, slightly modified to better simulate " 28 principles" , " web site click-through rate" and other power-law related issues.)

最大概然估计拟合直线，简单的使用最大概然估计拟合了直线，文件中给出了两张图片(MLE fit line（MLE for fitting a line pair）)

感觉方法不错，一种新的多尺度旋转不变性纹理特征提取方法(Feeling good method, a new multi-scale rotation invariant texture feature extraction methods)

Gardner 同步算法仿真。此m文件把Gardner算法的信号生成到发送，接收及同步一并给出。(Gardner Synchronization Algorithm Simulation. This m file to Gardner algorithm to generate a signal to send, receive and be given simultaneously.)

可实现双馈风力发电机在并网过程中的网侧模拟(Can realize double fed fan grid connected simulation)

数字信号处理基础.比较适合初学者，内容详尽，有不少高校用作教科书。(Based on digital signal processing. More suitable for beginners, detailed, many universities as textbooks.)

包含一本经典英文MIMO书籍中所有的图形的程序(MIMO contains a classic English books all graphics programs)

DQPSK仿真程序，包含调制解调、性能分析(DQPSK simulation program, including modulation and demodulation, performance analysis)
