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...
OFDM/OQAM is a special type of multi-carrier modulation that can be considered as an alternative to conventional OFDM with cyclic prefix (CP) for transmission over multi- path fading channels. Indeed, as it requires no guard interval, it has the advantage of a theoretical higher spectral efficiency. In this paper, we propose a new version of OFDM/OQAM named in short HS-OQAM, where HS means that an...
