matlab使用各种滤波函数实现图片的去噪处理(using the function denoising )

當一信號的進入角度若估計錯誤時，可利用其加以還原，使用apdaptive bemforming技術，能偵測出jammer在哪兒的源碼。(When a signal into the point of view, if the estimates wrong, it can be used to restore its use apdaptive bemforming technology, able to detect where a jammer source.)

产生模拟的GPS信号，可以研究与GPS信号相关的算法(Generating an analog GPS signals, the GPS signals can study related algorithms)

视频监控，如果有东西经过监控区域就语音报警（something is intruding）(Video surveillance, if there is something on the voice alarm through the monitored area (something is intruding))

自适应均衡领域的经典算法，最小均方误差算法（LMS）算法的数字均衡器建模源代码。建模建立了一个通信系统的收发两端，并模拟了信道衰减和噪声。并在接收端使用了数字均衡器。主程序中一次在接收端使用了自适应均衡器，另一次没有使用，可以清楚看到均衡前后误码率的差别。(The field of classical adaptive equalization algorithm, the minimum mean square error algorithm (LMS) algorithm for modeling digital equalizer source code. Modeling the establishment of sending and receiving ends of a communication system, and simulate the channel attenuation and noise. And at the receiving end using a digital equalizer. Once the main program at the receiving end using adaptive equalizer, another did not use, you can clearly see the difference before and after the equalizer BER.)

说明：  雷达信号脉冲多普勒的MATLAB源程序，可同时测得目标速度和距离信息(Doppler radar signal pulse of MATLAB source code, can be measured simultaneously target speed and distance information)

这是一个模糊pid控制的matlab程序。(This is a matlab program of fuzzy control pid.)

这个是对16QAM各种界的一个整理，给出了仿真程序，对于初学者来说具有重要的意义。(This is a finishing 16QAM various circles, the simulation program, for beginners is of great significance.)

一套科学运算语言 MATLAB 的程序设计有关的函数代码!!!(A set of scientific computing language MATLAB programming code related to the function!!!)

说明：  合成矩阵,将各列最大元素提出来，记录原来位置，形成新矩阵(Synthesis of matrix, the largest element of the proposed column, record the original position to form a new matrix)
