LDPCBSN
LDPC码既低密度奇偶校验码(Low Density Parity Check Code,LDPC),它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码,不仅有逼近Shannon限的良好性能,而且译码复杂度较低, 结构灵活,是近年信道编码领域的研究热点,目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G)
(LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)

NewtonRaphson
这个文档包含四种不同的功能求解非线性方程组。包括牛顿 - 拉夫逊,定点,正割,二分法方法。这项工作是我的课程的一部分,在数值计算的本科课程。它包括时序和表的打印输出进行分析和比较。有很多的观察,你可以:例如,对于一个特定的公式,一种方法可能运行的迭代次数最少,而另一个将运行更多的迭代,但计算速度最快的。(This document contains four different functions for solving nonlinear equations. Including Newton- Raphson, fixed, Secant, bisection method. This work is a part of my course in numerical undergraduate courses. It includes the timing and tables to analyze and compare the printout. There are a lot of observation, you can: For example, a specific formula, a method may be running a minimum number of iterations, while the other will run more iterations, but the calculation is the fastest.)
