QPSK

说明：  运用贝叶斯最小错误率法则识别手写数字，直接运行即可手写数字，然后识别。(Using Bayes minimum error rate rule to recognize handwritten numbers,directly run to handwritten numbers, and then recognize.)

此代码允许我们通过自相关技术 (1) 和震级的区别 （2） 计算出声音的音调 （基本频率）。这将与 lasdos 有更好的检测技术的沥青进行比较。

利用相关函数求信号功率谱,信号的自相关函数及不同信号的互相关函数(Use of correlation function for the signal power spectrum, the signal of the autocorrelation function and different signal cross-correlation function)

线性调频脉冲压缩(用于雷达方面)原理的简单介绍和matlab仿真程序(Chirp Pulse Compression (radar regard for) the principle of a simple introduction and matlab simulation program)

很不错的基于模板匹配的matlab程序，有意者可以下载下来看看吧(Very good based on template matching matlab program Interested parties can download to see it)

超像素就是把一幅原本是像素级(pixel-level)的图，划分成区域级(district-level)的图。可以将其看做是对基本信息进行的抽象(A superpixel is a plot of a pixel level, which is divided into a regional level. Think of it as an abstraction of basic information)

说明：  matlab锁相环解决相干光通信系统激光器相位噪声(Phase-locked loop to solve the phase noise of laser in optical communication system)

FM receiver based on TDA7040 chip, easy to accomplish

实用程序 对于初学MATLAB的人 很有帮助 也给编程节省不少时间()

仿真了在多径传播信道条件下仿真rake接收机的工作过程。接收机采用MRC方式，并考虑了降低接收机复杂性的不同方法。(Simulates channel estimation for a discrete-time channel impulse response hf with time resolution ts in seconds. In addition, the function uates the weighting factors to be used in a RAKE receiver implementing Maximal Ratio Combining.)
