Characterization and optimization of multicarrier technologies over PLC channel

I This paper focusses on the characterization and optimization of multicarrier technologies applied to PLC communications in the CENELEC band A. First, we will give a short description of the PLC test bench used by Schlumberger [1] and summarize the key tests that are applied to evaluate a communication technology. In the second part, we will present the key parameters of the multicarrier modulation. In the third part, we will present the performances of the multicarrier modulation. We will see that impulse noises have an important impact on performances. In the last part, we will suggest schemes to detect and attenuate the impulsive noises in the receiver.
