The performance of power line communication (PLC) systems suffer mainly from non-Gaussian noise, commonly referred to as impulsive noise. To reduce the effect of this noise, various channel coding techniques have been studied in the literature over PLC channels. Unlike existing works, in this paper we investigate the performance and robustness of polar codes over impulsive noise PLC channels for different...
Polar codes are regarded as a major breakthrough in modern channel coding since they are capacity-achieving using simple successive cancellation (SC) decoding. However, this is only possible with significantly large code lengths which may not be applicable for many systems. In this paper, we focus on short length polar codes and present a method which can enhance the performance of the successive...
In this paper, we propose a low latency fast Hadamard transform (FHT) based decoder for polar codes. We show that while this decoder can achieve the same performance as the popular successive cancellation (SC) decoder, it is superior to the SC decoder in terms of latency. The proposed FHT decoder can be applied directly to most short Polar codes, but requires a modest level of encoder modification...
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,...
