More robust decode-and-forward relaying over impulsive noise power line channels

Abstract

This paper discusses the issue of energy-efficiency in power line communication (PLC) systems and introduces decode-and-forward (DF) energy-harvesting based relaying. The performance of the proposed system is analyzed in terms of the energy efficiency for which accurate analytical expressions are derived. To highlight the achievable gains, we also evaluate the performance of both the conventional DF relaying and the directlink systems. The presented simulated results clearly demonstrate the correctness of our analysis as well as the advantage of the proposed system over the conventional relaying and direct-link approaches. Additionally, it is shown that the proposed scheme will become more energy efficient as the harvested noise energy becomes larger.

Incremental Relaying for Power Line Communication: Performance Analysis and Power Allocation

“…Furthermore, to address the relay selection problem for dual-hop transmission, a class of machine learning schemes has been proposed in [14]. Recently, DF energy-harvesting based relaying has been proposed for PLC and the issue of energy-efficiency has also been discussed in [15], [16]. Very recently, the ergodic achievable data rate of the so-called incomplete hybrid power line-wireless single-relay channel model has been studied in [17].…”
