The Influence of the Symbol Detection Error on Cooperative In-home Power Line Communication based on HS-OFDM Scheme

This work analyzes the influence of symbol detection error on cooperative in-home power line communication base d on channel estimates provided by a measurement campaign. We investigate cooperation communication based on a single relay model in which the relay node is situated in different locations between source and destination nodes by consider ing closed-form expressions of the maximum data rate of hermiti an symmetric orthogonal frequency division multiplexing sch eme with frequency domain equalizer based on minimum mean square error and zero-forcing criteria. The analysis is car ried out over the amplify-and-forward (AF) and decode-and-forw ard (DF) protocols together with maximal ratio combining techn ique. Numerical results show that the advantage of the DF protocol relative to AF one ends when the symbol detection error achie ves a threshold and this threshold depends upon relative locati on of the relay node regarding source and destination nodes.
