Estimating Shannon and Constrained Capacities of Bernoulli-Gaussian Impulsive Noise Channels in Rayleigh Fading

Relaying over power line communication (PLC) channels can considerably enhance the performance and reliability of PLC systems. This paper is dedicated to study and analyze the energy efficiency of multi-hop cooperative relaying PLC systems. Incremental decode-and-forward (IDF) relying is exploited to reduce the transmit power consumption. The PLC channel is assumed to experience log-normal fading with impulsive noise. The performances of single-hop and conventional DF relaying systems are also analyzed in terms of outage probability and energy efficiency for which analytical expressions are derived. Results show that using more relays can improve the outage probability performance; however, this is achieved at the expense of increased power consumption due to the increased static power of the relays, especially when the total source-to-destination distance is relatively small. Results also demonstrate that the IDF PLC system has better energy efficiency performance compared to the other schemes. -and-forward (DF), energy efficiency, impulsive noise, incremental DF, log-normal fading, multi-hop relaying, outage probability, power line communication (PLC).

“…This section presents a step-by-step analytical derivation of the energy efficiency expressions for the three systems considered. To calculate the energy efficiency (bits/Hz/Joule), we first calculate the average spectral efficiency (bits/s/Hz) which, in non-Gaussian channels, can be calculated as [16]…”

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.

This paper analyzes the performance of a multiple-antenna access point (AP) system with an energy-constrained single-antenna destination node in various Bernoulli-Gaussian impulsive noise environments. More specifically, we deploy the harvest-then-transmit protocol where communication is accomplished over two distinct phases: i) power transfer phase (down-link), ii) information transmission phase (up-link). In this respect, an analytical expression for the ergodic outage probability is derived and validated with Monte Carlo simulations. Results have shown that increasing the source transmit power or/and the number of AP antennas will minimize the ergodic outage probability. It is also presented that careful selection of the energy harvesting time is important to enhance the system performance.
