On enhancing the minimum Hamming distance of polar codes
Ammar Hadi, Emad Alsusa · 2016
Although polar codes can achieve the channel capacity in discrete memoryless channel, the practical performance of such codes, especially for the short ones, is still a subject of much needed improvement. The aim of this paper is to investigate increasing the Hamming distances of polar codes while maintaining their linearity property. We propose two methods; in the first, the code-rate remains unchanged, while in the latter, which produces superior performance, a modest reduction in the code-rate is incurred. It will be shown that both methods produce enhanced performance relative to the conventional polar codes.
