Impulse noise (IN) is one of the major impairments for data transmission over power lines. For power line communications (PLC) systems with bandwidths in the high kHz to MHz range, IN occurs in bursts. As long as those bursts are sufficiently short compared to a signal-processing (e.g. coding) frame, there is hope to successfully mitigate IN. In this paper, we introduce a new IN mitigation technique...
In this paper we investigate the performance of array codes and in particular generalised array codes (GAC) and row and column array codes (RAC) as coding schemes in the power line communications (PLC) environment. We apply different code rates and modulation techniques and we examine how these codes perform in the hostile channel of power lines in terms of BER (bit error rate) versus Eb / N0 (signal...
This paper proposes an improved decoding technique to remove impulsive noise effects on broadband powerline communication systems. Presented contribution deals with Home Plug 1.0 OFDM-based PLC scheme in presence of impulsive noise modeled by a stochastic distribution approximation. In order to improve receiver BER regarding impulsive noise effect and to reduce the complexity processing, a decoding...
In this paper we study how power line communications are affected by different coding techniques. We investigate the case of LDPC coding scheme and its application to the PLC channel. The modulation method applied is BPSK while the transmission technique used is OFDM. We study regular LDPC codes, which is the worst case scenario concerning the performance of LDPC codes. The OFDM symbol size is initially...
