逆傅里叶变化法的MATLAB程序

说明：  近年来，逆散射已经成为非常热门的话题，在这里我提交一个music算法的matlab例程，供大家参考。(In recent years, inverse scattering has become a very hot topic. Here I submit a matlab routine of music algorithm for your reference.)

关于蝶形宽带微带天线的设计 索引：蝶形宽带微带天线. 设计方案 排列效率 摘要：现在提出一种基于绝缘体衬底的有限长度的宽带微带天线的设计方法。这种方法快速、对计算精度要求较低，是建立在一蝶形天线进行二等分而形成的两个梯形天线的 。首先设计出单边的梯形部分，然后制作出相同的另一部分并在其顶点处将其连接。与理论计算相比在X波段上实验测量表现得很好。其有效带宽达到10.6％ (One approach to an antenna book starts with a discussion of how antennas radiate. Beginning with Maxwell’s equations, we derive electromagnetic waves. After that lengthy discussion, which contains a lot of mathematics, we discuss how these waves excite currents on conductors. The second half of the story is that currents radiate and produce electromagnetic waves. You may already have studied that subject, or if you wish to further your background, consult books on electromagnetics.The study of electromagnetics gives insight into the mathematics describing antenna radiation and provides the rigor to prevent mistakes. We skip the discussion of those equations and move directly to practical aspects.)

一种改进的EEMD信号处理方法,总体与EEMD方法相似，在白噪声的处理上更加科学（CEEMD)(An improved EEMD signal processing method, the overall similar to EEMD method, on the processing of white noise more scientific (CEEMD))

说明：  This code is related to the course Digital Communications. It simulates a communication system which uses AWGN and 16QAM
