polar-code:Matlab模拟极地代码-源码
Matlab simulation for polar codes
本程序只供学习交流使用，请勿用于商业目的。
注：本程序代码包含了 SC SCL BP SCAN和SSC译码算法
程序说明
polar码基本原理v1.docx叙述了polar码的基本原理
本程序给出一个主函数示例main,用户输入选择译码算法，以及译码参数
常用参数：
N: 码长，需为2的幂次
K: 信息位长度
码字构造参数:
design SNR: BA 构造方法的参数值
sigma: GA构造方法的初始值
SC译码时无参数
SCL译码时要求输入List大小和CRC校验位数
BP译码时要求输入迭代次数，一般为40；
SCAN译码要求输入迭代次数，一般为1-4；
SCL的CRC校验生成用了随机校验矩阵的方法，实验结果显示与标准CRC校验性能一致
SSC算法为SC算法的简化算法，速度提升明显
initPC是polar码初始化程
