阵列信号处理方面10个经典程序，包括波束形成，capon，MVCR等等，以及仿真图(10 classic program in array signal processing )

Mode locked lasers fiber code, I run it from appendix but its not working. Although I tried a lot to get it resolved. .m files are enclosed.

逆合成孔径雷达与对抗 图1.8

(1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请回答：证明自己用计算机产生的经典谱是正确的可能方法。 ((1) in certain wireless channel, the Doppler frequency shift will be caused by wireless channel output signal aliasing. Please describe the resulting aliasing of a variety of reasons (2) wireless channel Doppler spectrum there is a classical spectrum (classic spectrum), please explain such a spectral shape of the mechanism (3) Please use Simulink tools for writing code ( S-Function mode), resulting in a single Path Rayleigh channel, the Doppler spectrum for the classical spectrum, including mobile rate of 120km/h. And please answer: prove that they used computer-generated classical spectrum is correct possible ways.)

用matlab实现边缘细化的算法及原理，同时还有一个简单的例子帮助理解(With the edge of matlab implementation of the algorithm and the principle of refinement, at the same time have a simple example to help understand)

用matlab编写的图像压缩程序，可以实现图像的压缩(Prepared to use matlab image compression program, you can realize the image compression)

power_sfavg.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_sfavg.rar, ,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

本程序可以正常下载，运行。线性分组码定义，对于长度为n的二进制分组码，可以表示成（n，k），通常用于前向纠错。在分组码中，监督位加到信息位之后，形成新码，在编码中，k个信息位，被编为n位长度，（n-k）个监督码的作用是实现检错和纠错。(linear block code)
