| 摘 要： | 主要介绍了基于二元离散无记忆信道的极化码的构造以及相关性质。极化码不但能够在离散对称信道的条件下达到系统的对称容量,而且编译码的复杂度和码字长度几乎呈线性关系,即当码字长度为N时,其复杂度约为O（Nlog N）。最后讨论了极化码的应用以及研究热点。

| Abstract: | The construction and characteristics of polar code with binary discrete memoryless channel（BDMC） are introduced.Polar code can archive symmetric capacity under BDMC,and has almost linear complexity of the code block.When the code block is N,the complexities of both encoding and decoding are almost O（NlogN）.The application and recent research of polar code are also discussed. |
