基于差分进化的长度兼容极化码删余设计

Design of Puncturing for Length-Compatible Polar Codes Using Differential Evolution

Kuntal Deka, Sanjeev Sharma

摘要:

本文提出了一种删余技术来设计长度兼容的极化码。在差分进化(DE)的帮助下识别打孔比特。一个基于DE的优化框架开发的信息位的误码率(BER)值的总和最小化。我们确定了一组位,可以避免打孔的情况下,加性高斯白噪声(AWGN)信道。这减小了候选删余模式的大小。仿真结果证实了所提出的技术优于其他国家的最先进的打孔方法。

英文摘要:

This paper presents a puncturing technique to design length-compatible polar codes. The punctured bits are identified with the help of differential evolution (DE). A DE-based optimization framework is developed where the sum of the bit-error-rate (BER) values of the information bits is minimized. We identify a set of bits which can be avoided for puncturing in the case of additive white Gaussian noise (AWGN) channels. This reduces the size of the candidate puncturing patterns. Simulation results confirm the superiority of the proposed technique over other state-of-the-art puncturing methods.
