ldpc_distr
- LDPC码是Low Density Parity-check Codes的缩写，一个长为N的LDPC码由它的校验矩阵H来定义，该矩阵的特点是其中的元素0特别多，1特别少——即所谓的“低密度”。一个参数为（N，i，j）的H表示该矩阵中每列有i个1，每行有j个1，矩阵大小为N×K，N代表码字长度，K代表校验子的个数。 -LDPC code is the ab. of Low Density Parity-check Codes. A Length N LDPC is defined by its

HARQ
- 利用matlab仿真了改进的二类选择重传HARQ机制的吞吐量与误比特率之间的关系。在仿真中对于编码和解码过程进行了简化：根据误比特率按概率模拟传输过程中码字的出错位数，在接收端只判断码字错误的位数是否在可纠错得范围之内。每发送一个码字，接收端根据出错位数信息检验其是否出错，没有出错则接收，否则要求重发，程序中利用alternate值交替发送信息码字和校验码字。当校验码字到来后，若校验码与原码组成的新码字能够纠错，则正确接收，否则要求重传。 -Retransmission the HARQ mec
