Digital communication QAM32 generation

从BPSK到64QAM的调制与解调，方式可选！(From BPSK to 64QAM modulation and demodulation, optional way!)

matlab入门，一些基本规则，算法，书中还有一些实用的例子(matlab entry, some basic rules, algorithms, there are some practical examples of the book)

A simple PSNR calculator that might be handy in measuring the PSNR between two frames in a video. Typically used in measuring the distortion when videos are encoded and decoded.

调频步进信号的产生matlab方式。希望有用！(generating step frequency signal use matlab!)

信号在噪声幅值为1000倍时的提取和数据处理，相关滤波器的设计(Signal in the noise amplitude is 1000 times as extraction and data processing, correlation filter design)

image compression using JEPG2000

说明：  批处理画图，数据文件较多时，可以使用此程序进行批处理画图，获得直观的分析结果。(Batch drawing, large data files, you can use this procedure to batch drawing, to obtain an intuitive analysis.)

自学的必备工具之一,通过编程可以练习进行各种生产单位的实践工作(Self taught one of the necessary tools)

用BP网络逼近某曲线函数，在神经网络中邮广泛的应用 是系统辨识的基础。 通过反馈来不断的调整系数，限制了最大循环次数 防止进入死循环，当然如果想要得到更精确的系数可以增大循环次数。 (Using BP network function approximation to a curve, mail is widely used in neural network is the basis of system identification. Through feedback to constantly adjusted factor, limit the maximum cycle times to prevent into dead circulation, and of course if you want to get a more accurate coefficients can increase the cycles.)
