单负介质中matlab波导导模曲线单负介质中matlab波导导模曲线(Matlab single negative media guide curves of guided modes )

This is a matlab file of underwater communication field.

by ankush laddha。This system is active front end rectifier. It keeps the DC link at reference value, 400V in this case, even if load is suddenly changes. Also power factor is controllable so can act as STATCOM too. Control is based on synchronous frame theory and 2-level inverter is switched using Sine triangle PWM technique.(This system is active front end rectifier.

wav格式信号频谱分析，在matlab开发环境下可以很好的应用(wav format, the signal spectrum analysis, in the matlab development environment may be a good application of)

时域有限差分算法在求解三维电磁场中的算法公式(FDTD algorithm in the application of electromagnetic field)

一个Matlab实用教程，有编程基础，数值计算，矩阵，图形用户界面，接口等丰富的知识，一共31M，看大小也知道其含金量了(A Practical Guide Matlab, a programming foundation, numerical calculation, matrix, graphical user interface, interface, such as wealth of knowledge, a total of 31M, to see the size of its gold content is also aware of the)

说明：  Vblast，不同的编码方式qam，qpsk等，MMSE检测。不同天线数目设计。(very good for vblast MIMO beginners)

降维的mimo测向算法，基于music算法的mimo侧向算法 (reduced dimensional music algorithm)

this code explains the performance of BPSK and QPSK modulation techniques in terms of there bit error probability. this code plots the simulated bit error rate of bpsk and qpsk in terms of SNR. both modulation techniques are explained in RAYLEIGH fading channel.
