this is the noise reduction source code. i hope this will be useful for every body who used it

模拟噪声的程序，可以根据需要改写，主要功能是实现噪声模型 (Additive Noise Channel/Additive Guassian Noise Channel is the simplest of all channels. File usage details: op_channel = additivenoise(input_signal) mathematical Model: s(t) input signal to channel (=sig_ip) n(t)additive random noise process added by channel (=noise_mat) a(t) attenutation factor , here it is taken as random(=att_fact) out put signal r(t) = a .* s(t)+ n(t) an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal )

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

MATLAB在通信系统仿真 第二版书中例题代码(MATLAB simulation of communication systems in the second edition of the book example code)

此程序主要演示通道间相位误差对DBF旁瓣电平的影响。(This program is mainly to demonstrate of effect of channel phase errors on the sidelobes of DBF.)

一个简单的matlab通讯的小程序，希望对大家有帮助了(A simple sort of small procedures in the hope we have helped )

数据统计和分析的matlab程序，可作为数值分析等的学习工具。(Matlab program for statistics and data analysis can be used as numerical analysis , such as learning tools.)

very important to understand tomography of medical MRI images

说明：  卡尔曼滤波的一个典型实例是从一组有限的，对物体位置的，包含噪声的观察序列预测出物体的坐标位置及速度. 在很多工程应用(雷达, 计算机视觉)中都可以找到它的身影. 同时，卡尔曼滤波也是控制理论以及控制系统工程中的一个重要话题. 　　比如,在雷达中,人们感兴趣的是跟踪目标,但目标的位置,速度,加速度的测量值往往在任何时候都有噪声.卡尔曼滤波利用目标的动态信息,设法去掉噪声的影响,得到一个关于目标位置的好的估计。这个估计可以是对当前目标位置的估计(滤波),也可以是对于将来位置的估计(预测)，也可以是对过去位置的估计(插值或平滑). (kalman filter in matlab)
