# polar-coded-SCMA
***注:本程序只供学习交流使用,请勿用于商业目的。***
## 程序说明
1. 程序实现了polar码译码和SCMA多用户检测的联合检测译码问题,其中polar码译码采用SCAN软译码算法,SCMA采用MPA算法
2. 主函数包括四个子函数
- initPC:用于polar码编译码的初始化工作
- pencode:polar码编码
- scmaenc:SCMA编码映射
- JIDD:联合检测译码主函数
- SCMA检测--->polar码译码(SCAN算法)--->SCMA检测--->polar码译码(SCAN算法)-->......
- 参数:
- polar_N: polar码码长
- polar_K: polar码信息位长度
- alpha:论文当中的$\alpha$ 因子
- isInterleaver: 是否增加交织器
3. constructedCode文件夹下为构造的polar码码字
4. 仿真结果:
