PC码的BP解码,和传统的SC解码对比，有不错的优势-bp decoder for polar codes

通过找指数项和前后节点的关系，运用SC解码的极化码解码(By searching the relation between the index term and the front and rear nodes, the SC decoding is used to decode the polarization code)

极化码的构造编码以及各种译码方法的MATLAB仿真代码，可以直接调用函数。(The structure coding of polarization code and the MATLAB simulation code of various decoding methods can directly call the function.)
