“…The numerical analyses of the harvested energies are carried out with a data set composed of measures of additive noises, which was obtained from a measurement campaign carried out to measure the additive noise in the power lines and the air in in-home facilities. This data set was originally applied to analyze the PLC channel in the context of the spectrum sensing problem [10] in the frequencies of up to 100 MHz. The measurement campaign was carried out in 16 distinct residences spread over the urban area of Juiz de Fora, Brazil.…”

“…This work focuses on the evaluation of the suitability of EH from PLC and WLC additive noises inside residences for data communication purposes through hybrid PLC-WLC systems [8], [9]. These analyses are based on a set of measured additive noises, which were acquired from the power cable (PLC additive noise) and the air (WLC additive noise) measurement campaign [10]. Furthermore, the amount of energy that can be harvested from the additive noise in these media is used to evaluate achievable data rates in hybrid PLC-WLC systems.…”

Aiming to come up with strategies for harvesting energy in hybrid power line communication (PLC)-wireless systems, this work focuses on the amount of energy that can be potentially harvested from the additive noise in electric power grids and in the air within residential facilities when the frequencies from 1.7 up to 100 MHz are taken into account. Based on statistical analyses of a residential data set, we show that the average power of the measured additive noise in the power line is higher in the morning than other periods of the day. Also, it is higher than the values from the energy harvested from in the air, in the same frequency band. Moreover, we show that the amount of energy harvested from these additive noises can yield achievable data rates between hundreds of kbps up to dozens of Mbps if hybrid PLC-wireless channels are used for data communication purposes.

“…However, the usage of this spectrum can be scarce in different regions, what offers a chance for opportunistic sharing of the spectrum among primary users and PLC technologies (secondary users). For doing so, new generation of PLC technologies capable of monitoring and opportunistically sharing/reusing the spectrum with primary users is of great importance, what makes spectrum sensing techniques an ultimate and timely research topic [24]- [26].…”

Resumo-PLC (Power Line Communication)é uma tecnologia que vem sendo ciclicamente investigada tanto para comunicação em baixas taxas quanto em altas taxas. O interesse atual em oferecer comunicação via PLC para sistemas embarcadados, smart grid communications e a busca por inclusão digitalé elevado. As perturbações encontradas pelos sistemas para transportar dados usando PLC requer que novos esquemas e técnicas precisam ser encontrados para introduzir uma tecnologia de nova geração para PLC. Com estes aspectos em vista, abordamos neste artigo as melhorias e benefícios que podem ser obtidos com o uso de estratégias tais como comunicação cooperativa, comunicação cognitiva e comunicacção do tipo MIMO.

“…In general, spectral monitoring in the PLC system uses only signal extracted from a power line. However, [9] analyzed the use of signals extracted from power line and air, which is accomplished with the use of an antenna, for spectrum sensing purposes [10].…”

This paper introduces an improved spectrum sensing technique that exploits the existing information in the signals received from both electric power grids and wireless media to allow power line communication systems to monitor the spectrum occupancy/holes in the frequency band between 1.7 and 100 MHz. The applied procedure for implementing the proposed technique is organized in time-frequency mapping, selection and extraction of quanta, features extraction and selection, and detection. The attained results based on a measured data set show that the performance of techniques based on neural networks is far superior when compared to the techniques based on Bayes.
