关于Matlab的Tools的常见问题的介绍(Matlab s Tools on the Frequently Asked Questions Introduction)

This matlab code calculates a bit error rate of MIMO system based on MLD.

说明：  本Matlab程序是《现代信号处理》中利用MUSIC算法进行的谐波恢复的仿真程序(The Matlab program is )

《MATLAB语言－演算纸式的科学工程计算语言》，详细讲述Matlab编程入门，术语Matlab基础书籍(" MATLAB language- calculus paper-based scientific engineering computing language," a detailed account of Matlab programming entry, terminology Matlab based on books)

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)

POCS算法实现，较为全面，使用的一个程序。 (POCS algorithm)

卷积码编译码，用simulink模块搭建卷积码编译码，BPSK调制，仿真系统性能。(Convolution code encoding and decoding BPSK)

《MATLAB神经网络30个案例分析》中的第9个例子，案例9 离散Hopfield神经网络的联想记忆—数字识别。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 9, 9 cases of discrete Hopfield neural network associative memory- digit recognition. Hope to have certain help to everybody! )

matlab 程序代码 线性系统 龙格库塔法 可以解微分方程(matlab code linear system can solve differential equations Runge-Kutta method)

This is a simple function which caculates the spherical harmonic.The archive includes four M files ,and the file Comx_Sph.m is the main function.Given the degree l ,the index m and the variable x ,you can get the value of spherical harmonic.For more details ,you may read the programs.
