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：
