这是一份出色的瑞利信道下的OFDM信真论文(This is an excellent Fading Channel OFDM real paper letter)

提出了一种离散小波变换域实现图像水印的方法。这种算法充分利用小波变换的特点,把原始图像及水印图像塔式分解,在多分辨率分解后的相同的频段来嵌入水印信息。该方法也利用了人眼视觉特性,算法简单而有效。实验证明,该算法较好地解决了水印不可见性与鲁棒性之间的矛盾,对常见的水印攻击都有较强的鲁棒性。(presents a discrete wavelet transform domain image watermarking method. This algorithm using wavelet transform characteristics, the original image and the watermark image tower decomposition, Multiresolution decomposition in the same frequency band to the embedded watermark. The method has also been used HVS, the algorithm is simple and effective. Experiments show that the algorithm can solve the watermark is visible with the robust nature of, common to have more attacks watermark robustness.)

语音识别MFCC特征提取matlab代码。 「梅尔倒频谱系数」（Mel-scale Frequency Cepstral Coefficients，简称MFCC），是最常用到的语音特征，此参数考虑到人耳对不同频率的感受程度，因此特别适合用在语音辨识。(Speech recognition MFCC feature extraction matlab code. Mel cepstrum coefficient (Mel- scale Frequency Cepstral Coefficients, MFCC), is the most commonly used to the phonetic characteristics of this parameter given ear to the feelings of different frequencies, so especially suitable for use in speech recognition)

说明：  中值滤波是图像预处理中的一种较常用的方法， 它能有效去除椒盐噪声等的影响。(The median filter is the image preprocessing of a more common method, it can effectively remove the impact of salt and pepper noise.)

蚁群算法是一种用来在图中寻找优化路径的机率型算法。是一种求解组合最优化问题的新型通用启发式方法，该方法具有正反馈、分布式计算和富于建设性的贪婪启发式搜索的特点。通过建立适当的数学模型，基于故障过电流的配电网故障定位变为一种非线性全局寻优问题。(Ant colony algorithm is a method used to find optimal path in the graph the probability-based algorithm. Is a combination of optimization problems to solve new general heuristic method, which has a positive feedback, distributed computing and constructive and the greedy heuristic search features. Through the establishment of an appropriate mathematical model, over-current fault-based distribution network fault location into a nonlinear global optimization problem.)
