成果介绍

本发明公开了一种基于密度演进的极化码构造方法及极化码编译码系统，通过获取待处理的信息码的码长N及信息位长度K，计算N个比特信道对数似然比的概率密度函数的期望值集合，根据期望值集合选出K个比特信道作为信息比特信道，生成信息比特信道索引向量；将信息比特序列和固定比特序列混合，再将混合比特向量乘以极化码生成矩阵以输出编码序列；对编码序列进行调制后输入传输信道，并将传输信道输出的序列采用极化码译码算法进行译码操作，对译码后的编码计算误比特率和误帧率，改变设计信噪比，重复上述操作，直至误比特率和误帧率最小。本发明适用于一般二进制无记忆信道，误比特率和误帧率低，计算复杂度低，提高了通信系统的通信性能。
