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)
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)
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)
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 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)
The huge and increasing demand of data connectivity motivates the development of new and effective power line communication (PLC) channel models, which are able to faithfully describe a real communication scenario. This is of fundamental importance since a good model represents a quick evaluation tool for new standards or devices, allowing a considerable(More)
This paper deals with the secrecy guaranteed at the physical layer, namely physical layer security (PLS). The aim is to evaluate the achievable rate on the power delivery infrastructure, or power line communication (PLC) networks, under secrecy constraints. The focus is on the multiple-input, multipleoutput and multiple eavesdropper (MIMO-ME) wiretap(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)
