摘要
提出一个基于蒙特卡洛(MC)的构造方法,用于设计高维核矩阵极化码。证明当仿真次数趋向于无穷时,采用MC构造方法计算的位信道差错概率可以无限逼近实际差错概率。仿真结果表明,在连续消去和列表连续消去译码算法下,MC构造方法设计的极化码有着优于高斯近似构造方法设计的极化码。MC构造方法是一个有效的高维核矩阵极化码设计方法。
A Monte Carlo(MC)construction method for constructing polar codes with high-dimensional binary kernel is presented and analyzed.It is shown that the error probability of bit-channel calculated by the proposed MC construction method is accurate when the times of simulation goes to infinity.Simulations show that the MC construction method performs much better than the Gaussian Approximation-Density Evolution construction method under the SC and list SC decoders for polar codes with high-dimensional kernels.
