fc_B_rough

Realtime sound acquisiton and processing using matlab

Daubechies wavelet coefficients 4 to 8

matlab版本的数字信号处理，适合初学的人。(matlab version of the digital signal processing, suitable for beginners person.)

This matlab code can be used to find the nearest cluster head in the given cluster

该算法时LDPC码优化的好帮手。通过差分进化（DE）实现LDPC码度分布优化。给定码率，自动搜索最佳度分布。算法运算量较小，可以得到次优解。(The algorithm of LDPC code optimization is a good helper. Through differential evolution ( DE ) to realize LDPC code degree distribution optimization. Given rate, automatic search of optimal degree distribution. Algorithm can get smaller, suboptimal solution. )

Matlab中的智能控制代码，输入后修改参数再运行(Intelligent Control of Matlab code, input parameters and then run after the modification)

Bloom效果(附代码), 很酷的一个效果，效率不算高。互相交流一下。看看吧！(Bloom effect (with code), a cool effect, efficiency is not high. Exchange about. Let' s see it!)

最小二乘支持向量机的一个小程序，非常简单，也很耗用(Least Squares Support Vector Machines, a small program, very simple and consumption)

PID控制系统 对于系统的非线性 超调量 震荡等不稳定因素有很好的控制(PID control system for the nonlinear overshoot shocks and other uncertainties have very good control)

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印(Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection)
