摘　　要：现有极化码构造方案仅适用于二进制删除信道和加性高斯白噪声信道。为此,研究极化码在二进制对称信道(BSC)的构造方案。分析BSC中的极化码构造方式和编译码算法原理,利用连续删除译码算法对极化码在BSC中的纠错效率进行测试。仿真结果表明,蒙特卡罗法构造的极化码相对于巴氏参数法构造的极化码具有较好的纠错效率。The exisiting polar code construction scheme is only applicable to Binary Erasure Channel (BEC) and Additive White Gaussian Noise(AWGN) channel.Therefore,the constrution scheme of polar code in Binary Symmetric Channel (BSC) is studied.The construction method of the polar code and the principle of the coding and decoding algorithm in the BSC are analyzed.The error correction efficiency of the polar code constructed in the BSC is tested by the Successive Cancellation(SC) decoding algorithm.Simulation results show that the polar code constructed by Monte Carlo method has better error correction efficiency than the polar code constructed by Bhattacharyya method.
