The BCJR algorithm is an algorithm for maximum a posteriori decoding of error correcting codes defined on trellises (principally convolutional codes). The algorithm is named after its inventors: Bahl, Cocke, Jelinek and Raviv.[1] This algorithm is critical to modern iteratively-decoded error-correcting codes including turbo codes and low-density parity-check codes.

本程序用matlab编写，主要是为解决IEEE40节点电力负荷分配问题而想的一种算法。我把该算法命名为水桶法，是受一桶水的高度总与这个桶的最短一块木板齐平的原理，算法每次迭代把功率分配给需要最小消耗的机组上。(This program with matlab, main is to solve the IEEE40 node power load distribution and think of an algorithm. I put the algorithm named bucket method, by a bucket of water is the height of the barrels of the shortest total and a board at the principle, each iteration algorithm the power allocation to the minimum consumption on the unit needs. )

相位敏感光纤放大器的原理，核心思想是四波混频，用龙格库塔编程(The principle of phase sensitive optical fiber amplifier, the core idea is that the four wave mixing, Runge Kutta programming)

说明：  matlab 程序 是自己写的，太简单科别笑我 希望有人支持(matlab program is written in their own, too simple divisions laugh, I hope there is support for)

计算多重分形非趋势波动分析matlab程序,基于K均值的PSO聚类算法,旋转机械二维全息谱计算。( Calculation multifractal detrended fluctuation analysis matlab program, K-means clustering algorithm based on the PSO, Rotating machinery 2-d holographic spectrum calculation.)

说明：  针对小流域设计洪水计算中，采用推理公式求解洪峰流量Qm及汇流时间τ的方法繁琐，查算精度较低等问题，提出用牛顿迭代法求解，该方法较原图解试算法收敛快，迭代次数少，计算速度快，精度可靠。计算实例表明，用简单迭代法与牛顿迭代法计算设计洪峰流量，其结果与图解试算法完全一致。()

函数用来对一个三维矩阵A，输出最大元素值的三维坐标值。(Function is used on a three-dimensional matrix A, the output value of the maximum element of three-dimensional coordinates.)

说明：  最小二乘递推算法RLS，利用递推最小二乘法计算Volterra级数的核(recursive least squares algorithm RLS using recursive least squares method Volterra series of nuclear)

图像RGB颜色矩提取matlab程序，有注释,有需要的拿去(Image RGB color moments extraction procedures, there is a comment)

说明：  基于Matlab的MIMO通信系统仿真”，收获良多，特将其记录下来，与诸位分享。此主题分为上下两部分，第一部分主要涉及系统架构，第二部分侧重程序优化。若能帮助读者一二，实属万幸。(Multi-input multi-output (MIMO) communication system based on Matlab simulation ", so, will its record, share with you. This topic is divided into two parts, the first part mainly involves the system architecture, the second part focuses on process optimization. If can help readers just a little, is lucky.)
