timing recovery carrier program

，用MATLAB实现快跳频通信系统的仿真。主要应用了SIMULINK和COMMUNICATION BLOCKETS两个模块。整个设计包括了信源产生部分、发送部分、跳频调制部分、信道部分、接收部分和结果分析部分共六个模块，核心技术是伪随机序列的产生和频率合成器的设计，而关键技术是收发两端的伪随机码元的同步。伪随机码的产生用S－函数编程来开发自己的SIMULINK模块。同步的实现是收发两端采用相同的扩频脉冲触发。而且在设计中每个模块都采用了模块封装技术，从而简化了框图结构(Using MATLAB to achieve fast frequency-hopping communication system simulation. The main use of SIMULINK and COMMUNICATION BLOCKETS two modules. The whole design, including part of the generated source, sending part of some frequency-hopping modulation, channel of the receiving part and the results of analysis of part of a total of six modules, the core technology is the emergence of pseudo-random sequence and frequency synthesizer design, and the key technology is the transceivers at both ends of the pseudo-random synchronization symbol. Pseudo-random code generated by S-function programming to develop their own modules SIMULINK. Synchronization is used to send and receive ends of the same spread-spectrum pulse trigger. But also in the design of each module using the module packaging technology, which simplifies the structure of the diagram)

对正选信号进行仿真，并分别通过时域和频域对其延迟，对比延迟效果(A signal being selected for simulation, respectively, through the effect of the time and frequency domains its delay, Comparative delay)

我在毕业设计时做的一个MATLAB实现图像的SIFT特征提取程序，并做在不同光照、不同视角下的 vZnbfT 特征匹配，还做了 zSCjeKh 特征值的提取转换，编译通过(I graduated the design of a MATLAB to achieve the image of the SIFT feature extraction process, and do in different light, different angles of the vZnbfT feature matching, but also to do the zSCjeKhfeature extraction and conversion, the compiler through)

说明：  噪声射频干扰信号的matlab仿真实现，其中包含成像的提取程序(SAR radio frequency jamming signal)

说明：  使用BP算法实现异或功能，由matlab编程实现，可正确运行。(BP algorithm using the XOR function, the matlab programming, can be run correctly.)

8psk的解调doc文章，超级有价值，可以用于工程实践。(8PSK demodulation doc articles, super valuable and can be used in engineering practice.)

在matlab环境下，对自定义目标的修改，讲解tlc文件，main文件的含义。(In the matlab environment, modify the custom targets, explain tlc files, main file meaning.)
