Sullivan Dennis的electromagnetic simulation using fdtd method一书中代码MATLAB版(Sullivan Dennis--electromagnetic simulation using fdtd method MATLAB)

这是由Andrea Monti Guarnieri的卫星轨道确定算法，基于的是norad 的tle数据(This is Andrea Monti Guarnieri satellite orbit determination algorithm, is based on the norad of tle data)

包含一份程序代码、一幅运行结果图和一篇说明文档。用于电力系统稳态分析的程序，是PQ法潮流计算的典型应用，针对四机十一节点的电力系统，经仿真测试通过，有较强的参考价值。 (It contains a copy of the program code, the results of a run and a diagram documentation. A program for steady-state analysis of the power system, a typical application PQ load flow calculation method for the four planes eleven nodes power system, the simulation test is passed, there is a strong reference value.)

RS编解码的Matlab源代码，拿来和大家分享(RS codec Matlab source code, used to share)

根据图片手动选取像点，根据一定的组合顺序选择一定数量的像点，进行摄像机标定内外参数(According to the pictures manually select the image, based on a combination of a series of selecting a certain number of points, inner and outer parameters of camera calibration)

matlab下实现的波束形成技术，利用的是ETAM算法进行合成孔径，增加虚拟阵元个数，以提高定位精度。(matlab achieve beam forming technology, the use of the synthetic aperture ETAM algorithm to increase the number of the virtual array elements in order to improve positioning accuracy.)

QAM simulator for AWGN, multipath channel

UWB-Run from editor debug(F5)-PPM(pulse position modulation) of UWB monocycle and doublet waveforms. This m file plots the time and frequency waveforms for PPM 1st and 2nd derivative equations used in UWB system analysis. Fudge factors are required to correct for inaccuracies in the 1st and 2nd derivative equations. Tail to tail on the time wave forms must be considered as the actual pulse width.

说明：  牛顿拉夫逊法用MATLAB如何实现其功能，在迭代过程中如何使用循环算法(Newton-Raphson Power Flow)

一个很经典的Turbo编码解码程序，除了Turbo码的性能测试外，还增加了正常的信源编码和解码过程，主要用于通信中的信源数据的编码和接收端得解码过程。(The encoding.com turbo encoding feature is available via the encoding.com API and will automatically send your job to a higher capacity (more CPU and more RAM) server for faster processing times. This feature is great to use for high bitrate, H.264, HD, or any video encoding job in which processing time is critical. On average the turbo encoding feature will process a job 60 faster than our standard servers. )
