ONDULEUR DE TENSION TRIPHASE IN THE ONE BLOCK

THIS IS A MATLAB CODES TO SIMULATE 16 QAM Bit Error Rate for 16-QAM modulation using Gray modulation mapping

《提问的智慧》，作为一个程序员，你曾经遇到过在论坛上发帖无人问津，看看提问的智慧把(" Question the wisdom" as a programmer, you have encountered no one is interested to post in the forum to see the wisdom of the questions)

说明：  QR分解是球形MIMO检测算法必不可少的环节,本代码采用m语言描述了QR分解分解具体怎么实现,而不是直接调用matlab内部函数,采用的是QR分解的脉动阵列结构,据此代码可轻易实现QR分解的FPGA设计(QR decomposition is an essential part of the spherical MIMO detection algorithm, the code uses QR decomposition decomposition m language to describe specifically how to achieve, rather than a direct call matlab internal function, using the QR decomposition systolic array structure, pursuant to which the code can be easily QR decomposition FPGA design)

高斯加性模拟信道，模拟仿真高斯白噪声情况下信号传输情况(additional noise channel)

本人改进的关于自适应分割方法，结合了大津法获得的阈值作为初始阈值，可以提高运行速度和分割效果(I improved on the adaptive segmentation method that combines the Otsu threshold obtained as the initial threshold, can improve speed and segmentation results)

说明：  matlab算法练习，包括牛顿迭代法，赛德尔迭代法等(matlab learning)

good code Files: (see file headers, or type help file in MATLAB, for more info) README - this file trainEM_tree.m - function that takes a wavelet transform, a number of states, and a maximum number of iterations and returns HMT parameters. No convergence criteria is specified right now (easily fixed), it just runs a specified number of iterations (default 30).
