Abstract :
The power line channel is characterized by a multipath behavior. A direct consequence is that multi-carrier modulation (MCM) is generally retained for power line communication (PLC). In addition to OFDM, or equivalently DMT, wavelet OFDM and Hermitian symmetry OFDM/OQAM (HS-OQAM) have been recently proposed for PLC transmission. In this paper we propose a unified and efficient modulation scheme that can generate all these different modulation schemes.
