doa估计经典music 算法 构造简单入射信号,利用7天线阵接收信号,进行波达方向估计.(doa estimated classical music used to construct simple incident signals, using seven antenna reception of signals for DOA estimated.)

代码实现了最小均方差和迫零均衡器的误码率仿真图，并且通过对比理论曲线，验证了代码的正确性。(Code implements the MMSE and zero forcing equalizer BER simulation diagram, and by comparing the theoretical curves to verify the correctness of the code.)

prony算法,复指数函数的线性组合来描述等间隔采样数据的数学模型。(prony algorithm，Linear combination of mathematical models to describe the complex exponential function equally spaced sampling data)

把信号分为重叠或不重叠的小段，对每小段信号序列进行功率谱估计，然后取平均值作为整个序列的功率谱(The signal into overlapping or non-overlapping short paragraphs, short paragraphs on each of the power spectrum estimation signal sequence, and then averaged Fourier power spectrum as a whole)

说明：  本程序实现了短数据序列不同窗函数的welch功率谱估计，然后又求了他们的平均标准差，从而判断各个窗函数的优劣。只要稍作修改就能实现不同信噪比下的功率估计，同时也可以实现长数据序列的估计。(This procedure has a short data series of different welch window function power spectrum estimation, and then seek their average standard deviation, and thus to determine the merits and demerits of each window function. As long as we can with some slight modifications under different signal to noise ratio power estimate, but also the realization of a long data sequence can be estimated.)

Chebyshev和Legendre展开(Chebyshev and Legendre expansion)

路径损耗的仿真程序，比较简单，但很常用的啊(path loss)

ASM 主动形状模型 MATLAB代码 （用于分割）(The ASM active shape model MATLAB code (for split))

时频分析的小帮手，里面对基本的时频分析程序有了比较详细的论述(Time-frequency analysis of the Companion, which the basic time-frequency analysis program with a more detailed exposition)
