matlab实现MUSIC算法,信号样本数1000，估计自相关矩阵为八阶。(matlab to realize music algorithm)

说明：  地震数据时频分析与分频处理，需要的带走吧，很不错的(Time-frequency analysis and seismic data processing division, need take it away, it is good)

针对稀疏圆阵的波达方向估计问题，提出了解相干求根MUSIC算法（Sparse UCA Decorrelation Root-MUSIC，SDR）。通过改进传统的波束变换方法，进行相位校正，并在波束域进行误差补偿，得到具有共轭对称结构的波束域导向矢量。在波束域进行前后向平均处理和使用求根MUSIC算法(In order to solve the direction of arrival estimation of sparse circular arrays, a new understanding of the Sparse UCA Decorrelation Root-MUSIC (SDR) algorithm is proposed. By improving the traditional beam transform method, phase correction, and error compensation in the beam domain, a beam-domain steering vector with a conjugate symmetry structure is obtained. Averaging forward and backward in the beam domain and using the root-finding MUSIC algorithm)

这是MATLAB图形界面设计（英文原版），有需要的下下来看吧(MATLAB graphical interface design (English original), there is a need in the next down and see)

Driver for Digigram miXart soundcards.

说明：  1/3倍频程的实现，先fft然后计算上下限频率。(The realization of 1 / 3 octave, FFT first and then calculate the upper and lower frequency.)

详细的kalman滤波程序,对于初学者很有用(kalman filter)

说明：  matlab实现经典功率谱估计,xiwangdajia xuexi(matlab gonglvpugyujichengxu)

霍夫曼编码的具体方法：先按出现的概率大小排队，把两个最小的概率相加，作为新的概率 和剩余的概率重新排队，再把最小的两个概率相加，再重新排队，直到最后变成1。每次相 加时都将“0”和“1”赋与相加的两个概率，读出时由该符号开始一直走到最后的“1”， 将路线上所遇到的“0”和“1”按最低位到最高位的顺序排好，就是该符号的霍夫曼编码。(Specific methods Huffman coding: the probability of emergence of the size press line, the two smallest sum probability, as a new probability and the probability of re-queue the remaining, then the minimum of two probabilities are added, and then re-queue, until finally become one. Each time the sum will be 0 and 1 Fu added two probabilities, when read by the symbol has come to begin the final 1 , the route will encounter a 0 and 1 at the lowest to the highest bit of the right order, that is the symbol of the Huffman coding.)
