说明：  DTMF双音多频检测，输入一组电话号码，可以检测出输入的电话号码是多少(dtmf detection)

matlab图像分类分割编程 利用matlab 的fuzzy分类为图像分类编写的matlab程序(image classification segmentation matlab programming)

Given 2 subscripts, j & k, KronD will return 1 if j == k and 0 if j != k. A very simple function with only a single if-else statement. Saves a bit of typing when the Kronecker Delta is needed.

不错的OFDM系统仿真程序。包括了整个系统所需的仿真程序。(Good OFDM system simulation program. Including the entire system simulation program required.)

二维DOA估计,文件不是很长，还是比较好用的，希望能对大家有所帮助(use for two-dimension DOA estimate.)

matlab的Simulink仿真实例，原版英文资料，比较基础。(Matlab Simulink simulation instance, the original information in English, the basis for comparison.)

多种esprit算法的对比仿真分析，通过对比，可以知道哪种算法最适合(Contrast variety esprit algorithm simulation analysis, by contrast, can know what the most appropriate algorithm)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)
