代码说明:

  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.)

    将Iris数据集分为2组,每组各75个样本,每组中每种花各有25个样本。其中一组作为以上程序的训练样本,另外一组作为检验样本。为了方便训练,将3类花分别编号为1,2,3 。   使用这些数据训练一个4输入(分别对应4个特征),3输出(分别对应该样本属于某一品种的可能性大小)的前向网络。(The Iris data set is divided into two groups each of 75 samples in each group have 25 samples in each flower. One set of sample programs as more training, another group as the test samples. To facilitate training, the three types of flowers were numbered 1,2,3. Training before using these data a 4-input (respectively 4 features), 3 outputs (respectively the possibility should belong to a variety of sample size) to the network.)
