LMS滤波算法，分别对锯齿波、方波、正弦波进行了滤波，并将滤波前后的信号进行了对比，很好的恢复出了真实信号。(LMS filter algorithm. The sawtooth wave, square wave, sine wave are filtered, and the signals are contrasted before and after filtering. The real signals are all well recoveried by this algorithm.)

说明：  里面是很多matlab的常用功能举例，matlab有很多用法不为我们所知，又因为matlab的帮助文件是英文的，看起来费劲，而这个压缩包就有很多matlab用法的举例。(Inside is many matlab commonly used function examples, matlab has many usages not to know for us, also, because the matlab help file is English, looks like uses energy, but this compression package has many matlab usage example. )

通过将喷泉码的编译码方法再无线衰落信道上的用matlab仿真出来(Multi-path ruili channel simulation research on matlab)

在matlab中运行可以生成高斯随机粗糙表面，可以作为粗糙面模拟的准备工作。(Run in matlab can generate Gaussian random rough surface, rough surface can be used as an analog preparations.)

本程序基于约瑟夫森结的RSJ模型，对无微波辐照和微波辐照下约瑟夫森结的特性进行了数值计算求解，其中有微波辐照的RSJ模型求解采用了四阶龙格库塔方程函数，两种情况都给出了I-V特性曲线图（程序包中也附带），展现了量子化电压台阶。(This procedure based on the RSJ Josephson junction model, no microwave radiation and microwave radiation characteristics of Josephson junction has been calculated solving, in which microwave radiation has the RSJ model for solving a fourth-order Runge-Kutta equation function In either case, they are given IV characteristic curve chart (also included with the package), demonstrating the quantum level of voltage.)

图像去噪 小波分析 去噪效果一般 欢迎大家交流指正(image denoise)

the comb pilot aided channel estimation in ofdm modulation is considered. the power of pilot subchannels is under the control. The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

说明：  CA 和其改进 RELAX 算法的实现 对估计密集谱及弱频率成分有很好的效果( The implementation of CA and its improved algorithm RELAX have a good effect in estimating the intensity and weak spectrum of frequency components)
