说明：  matlab对脉搏信号的去噪、滤波、特征提取。(Matlab denoising, filtering and feature extraction of pulse signal.)

说明：  一种很好的针对非平稳信号的一种算法，他可以有效是区别各种调治方式，是对以前的时间平滑方法的一种改进形式，希望对大家有用(A good response to non-stationary signals in an algorithm, he can be an effective way to distinguish between the various modulating is a smoothing method before the time of an improved form, in the hope that useful)

说明：  一些时反的例程和其他代码，mat文件是信道信息(The Mat file is the channel information. There are some examples of the Time Reverse and communication system.)

说明：  主动锁模光纤激光器，利用强度调制器在腔内产生周期性的损耗调制，产生了超短脉冲。(Active mode-locked fiber)

用matlab实现简单的bpsk系统，熟悉bpsk系统的特性(Implementing BPSK with MATLAB)

log算子检测斑点程序，程序可读性好，检测结果也不错，可以自行加载自己的图片进行检测(log operator to detect the spots on the program, the program readability test results are good, you can load your own picture to detect)

Example code with images for assessment of SAR images using image registration and feature based techniques

说明：  在AM信号中，载波分量并不携带信息，仍占据大部分功率，如果抑制载波分量的发送，就能够提高功率效率，这就抑制载波双边带调制DSB-SC（Double Side Band with Suppressed Carrier），简称双边带调制（DSB）。(In AM signal, the carrier component does not carry information and still occupies most of the power. If the transmission of the carrier component is suppressed, the power efficiency can be improved. This is called double side band with suppressed carrier (DSB for short).)

主要关于卷积码的程序实现，有源代码及运行结果。(Convolutional codes is mainly concerned with the program, source code and operating results.)
