Case Study – Loud Speaker Drive with Matlab implementation

包含了一个运行良好的蚁群算法，采用了自衰减的蚁周改良(Contains a well-ant colony algorithm, using ant from the decay of the Week improved)

n-queens implementation in MATLAB

内有两个MATLAB程序，主要用于语音增强：一个用于向纯净语音文件(wav)添加高斯白噪声，信噪比可选；另一个文件用于测量语音信噪比，对语音增强效果判断(MATLAB, there are two procedures, mainly used for speech enhancement: one for the pure audio files (wav) add white Gaussian noise, SNR optional another document used to measure the voice signal to noise ratio, the effect of speech enhancement judge)

提出了一种改进的LTE系统接入方式,用MATLAB进行了性能仿真。(advance a modified access mothod of LTE system，by using the MATLAB to siumlink the performance of this new method)

改进的k均值算法，可以加速运行时间，详见Using the Triangle Inequality to Accelerate k-Means(Improved k-means algorithm, can accelerate the running time, see Using the Triangle Inequality to Accelerate k-Means)

显示图像，估计图像背景，直方图均衡化，二值化等基本操作(show figures,estimate background of figure)

自适应均衡器设计，采用分数间隔、判决反馈结构，MMSE算法。(Adapt a FSE+DFE combination for square M-QAM over T/2-spaced microwave channels with AWGN initialized by Unbiased MMSE-FSE receiver )

自己编写多点采集数据处理程序，用于数值仿真多点采集，很好得到一个平均曲线，非常好用，用COMSOL仿真后处理，读CSV文件格式(Write your own multi-acquisition data processing program for the numerical simulation of multi-point acquisition, good to get an average curve, very easy to use COMSOL simulation post-processing, read the CSV file format )

基于小波包分解的语音去噪，根据熵谱概率密度函数估计阈值，去除实际环境噪声。(Based on wavelet packet decomposition of the voice de-noising, in accordance with spectral entropy probability density function estimated threshold, the actual removal of environmental noise.)
