Algortihms to estimate blocks of an image

包括了MATLAB中常用函数，是Matlab 初学者的好帮手。(Commonly used functions, including the MATLAB is Matlab beginners a good helper.)

上海交大硕士毕业论文《基于最小熵谱估计的 高频重建算法研究》：本论文提出了一种基于最小熵谱估计的高频重建算法（论文中简称为（MEHFR），该算法利用最小熵准则对信号谱进行外推，从而重建出音频信号的高频分量，论文同时对提出的MEHFR算法作了改进和性能分析，并给出了MEHFR成功应用于目前主流音频编解码器——MP3的一个实例(This thesis puts forward an algorithm of high frequency reconstruction based on minimum entropy spectral estimation (called MEHFR in this thesis). MEHFR spreads the spectrum in the principle of minimum entropy and reconstructs the high frequency of audio signals also this thesis improves MEHFR and shows the analyses of performance at last applies MEHFR to ME3 which is the most popular codec of audio.)

说明：  非正弦信号的波束形成程序，和利用相位的常规波束形成不同，非正弦信号的波束形成首先匹配滤波，提取包络，然后延时相加，(Non-sinusoidal signal beamforming process, and the use of conventional beam-forming phase is different from non-sinusoidal signals in the first match beamforming filtering, envelope extraction, and then add delay,)

这是用matlab编写的一个kalman滤波器，数字信号实验维纳滤波，估计AR模型参数(using Matlab is prepared by a Kalman filter, digital signal experimental Wiener filtering, AR model parameters estimated)
