This paper focuses on the benefits of the existing relationship among consecutive subchannels (spectral information) in a multi-carrier modulation-based power line communication system for reducing the computational complexity and signaling overhead associated with resource allocation techniques. In this regard, we introduce the spectral compressive resource allocation technique, which reduces the...
This work outlines a procedure for choosing the gap from the Shannon capacity curve in order to solve resource allocation problems in orthogonal frequency-division multiplexing-based power line communication systems impaired by impulsive Gaussian noise. In this regard, we perform statistical analyses of additive impulsive Gaussian noise models in order to measure the effect of the noise information...
This work analyzes different error-correcting schemes for combating the effects of narrow-band interference in coded orthogonal frequency-division multiplexing-based narrow-band power line communication systems. In this sense, we analyze an error-correcting scheme widely acclaimed in the literature, which is constituted by the concatenation of a Reed-Solomon (RS) code, a convolutional code and an...
We consider a multi-channel power line communication (PLC) system, where channel coefficients follow non-identical log-normal distributions. We assume that statistical characteristics of each channel are time-variant, or in other words, channels are non-stationary. In such scenario, we formulate a channel selection problem, where a transmitter, provided with no prior information, aims at selecting...
A brief introduction to MIMO-PLC as well as the special case of SIMO-PLC is provided. It is shown that in MIMO-PLC channels, a spatial correlation is inevitable and channels are not spatially independent. A physical as well as a mathematical description of the spatial correlation in MIMO-PLC is provided. Furthermore, two reception diversity techniques, Maximum Ratio Combining (MRC) and Equal Gain...
