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.)

Load_V2.0
此程序根据王专利撰写的《翼面结构有限元模型节点气动载荷计算》编写
需要的前期准备文件:case01.txt---已知不同工况下各个载荷点力的文件
Force_Site.txt---已知各个载荷点的坐标
Node_Site.txt----有限元节点坐标
输出文件 Nodal_Force_01.txt----存放每个有限元节点计算后分得的力,第一列为节点编号,第二列为节点力大小(This process patent under the king wrote " wing structural finite element model node aerodynamic load calculation" Writing required preparatory documents: case01.txt-- known under different conditions of each load point force file Force_Site. txt--- known each load point coordinates Node_Site.txt---- finite element nodal coordinates output file Nodal_Force_01.txt---- storage node finite element calculation for each share of power, first as the node number, the second column is the size of nodal forces)
