Partial-Fourier Reconstruction with POCS

此程序模拟了17X11的正方形光子晶体点阵作为能量偏分器的动态过程。(This program simulates a 17X11 square photonic crystal lattice energy as a partial divider dynamic process.)

用计算机进行数字图像处理，使用matlab环境，对图像进行增强，平滑与锐化，分割，变换，压缩与编码，是平常实验的好选择。(Using computer digital image processing, the use of matlab environment, enhance the image, smoothing and sharpening, segmentation, transform, compression and encoding, is usually a good choice experiment.)

this file is related to qpsk quadrature phase shift keying mod. in fading channel..which is helpful in desgining a channel with qpsk mod technique

中继增强的LTE-A蜂窝网络中路由方案的优化.pdf(Optimization .pdf relay enhanced LTE-A cellular network routing scheme.PDF)

对二维结构进行拓扑优化，基于变密度法的二维mbb梁的结构拓扑优化，迭代采用优化准则法，数值不稳定采用灵敏度过滤法。(Two-dimensional structure topology optimization, based on the variable density method of two-dimensional the MBB beam structure topology optimization, iterative optimization criteria, the numerical instability sensitivity filtration.)

这是基本的人工鱼群算法的matlab程序的实现，方便理解和学习(This is the realization of the basic artificial fish swarm algorithm matlab program to facilitate understanding and learning)

Robust PID Controller Design for an UAV Flight Control System

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)
