—A statistical characterization of the in-home power line communication channel is performed from the study of a wide set of measured channels in the 1.8–100 MHz frequency band. The study provides new insights on a) the relation between the line impedance and the channel frequency response (CFR), b) on the spatial relation between the channels that share(More)
We study the performance improvement provided by the use of precoding schemes in multiple-input multiple-output (MIMO) power line communications (PLC) in the presence of additive colored and correlated Gaussian noise. We assume a power spectral density constraint, according to the HomePlug AV2 standard, and we focus on a 2 × 4 MIMO system, thus(More)
We consider confidential data communication over power line communication (PLC) networks. In particular, rather than analyzing cryptographic techniques, we focus on the security provided at the physical layer, named physical layer security (PLS). Although physical layer security is widely discussed for wireless systems, we can not say the same for the PLC(More)
—In recent decades, power line communication has attracted considerable attention from the research community and industry, as well as from regulatory and standardization bodies. In this article we provide an overview of both narrowband and broadband systems, covering potential applications, regulatory and standardization efforts and recent research(More)
SUMMARY This paper provides an overview of power line communication (PLC) applications, challenges and possible evolution. Emphasis is put on two relevant aspects: a) channel characterization and modeling, b) filter bank modulation for spectral efficient transmission. The main characteristics of both the indoor channel (in-home, in-ship, in-car) and the(More)
—We consider the secure transmission of information over power line communication (PLC) networks. The focus is on the secrecy guaranteed at the physical layer, named physical layer security (PLS). Although PLS has been deeply investigated for the wireless case, it is not the same for the PLC environment. Thus, starting from the knowledge in the wireless(More)
This paper proposes a synthetic statistical top-down MIMO power line communications channel model based on a pure phenomenological approach. The basic idea consists of directly synthesizing the experimental channel statistical properties to obtain an extremely compact model that requires a small set of parameters. The model is derived from the analysis of(More)
context of in-vehicle data networks. This technology can provide high-speed data connectivity via the exploitation of the existing power network, with clear potential benefits in terms of cost and weight reduction. The focus is on two scenarios: an electric car and a cruise ship. An overview of the wiring infrastructure and the network topology in these two(More)
