粒群算法寻找好绕过障碍一点到另一点的最优路径(Particle swarm algorithm for finding good around the obstacle one point to another point of the optimal path )

此算法对阵元信号进行估计，仿真结果显示其有效性(dmusic estimation)

文件包含两个m文件，一个是QPSK的主函数文件和单径的瑞利衰落信道fade.m文件，实现的对qpsk的过程进行了仿真（在瑞利和高斯信道的作用下）。绘制出了在各个阶段的波形图(M file contains two files, one file is the main function of QPSK and single path Rayleigh fading channel fade.m file qpsk the process of implementation of a simulation (in the Rayleigh and Gaussian channel under the action.) Drawn out at each stage of the waveform)

说明：  一些ofdm同步算法的经典文献，初学者必看，不可错过(Some ofdm synchronization algorithm of the classic literature, beginners must see, not to be missed)

提出了一种基于小波变换和模糊集的图像融合算法.其基本思想是: 首先对图像进行小波变换,获得图 像的低频和高频分量 随后在融合过程中, 对低频和高频分量采取不同的融合策略, 即对低频分量采用平均能 量法进行融合,对高频成分利用图像的模糊集, 寻求一个模糊隶属函数作为融合算子进行融合 最后再对融合 后的图像进行小波反变换,重构出融合后的图像.实验结果证明了方法的有效性.(Proposed image fusion algorithm based on wavelet transform and fuzzy sets. The basic idea is: First the image wavelet transform to obtain the low and high frequency components of the image followed by low and high frequency components in the fusion process to take a different the integration of strategy, integration of the low frequency components using the average energy method, the use of high frequency components of the image fuzzy sets, look for a fuzzy membership function as a fusion operator for fusion image fusion wavelet transform and re- structure of fused images. experimental results demonstrate the effectiveness of the method.)
