With the HPAV specification, windowed OFDM is now the most commonly used modulation technique in PLC networks. However, another modulation, named OFDM/OQAM, could notably improve the capacity of these networks. Imposing an orthogonality condition only in the real field, this modulation offers a great flexibility in the design of the prototype filter that shapes its symbols. Nevertheless, to take advantage...
Orthogonal frequency division multiplexing (OFDM)/discrete multi-tone (DMT) has been proposed as a suitable modulation for power-line communications. However, its drawbacks, e.g., bad frequency localization and spectrum efficiency loss due to cyclic prefix (CP) appending, are also obvious. On the other hand, the hermitian symmetric (HS) version of OFDM/OQAM modulation has been presented as a good...
OFDM/DMT has been proposed as a suitable modulation for power-line communications (PLC). Meanwhile, another modulation, named OFDM/OQAM, was presented to be also an alternative to OFDM. Further, the HS-OQAM system was proposed particularly for the baseband communications such as PLC. This paper gives a theoretical expression of the inter-symbol interference (ISI) plus inter-carrier interference (ICI)...
We address the challenges related to the development of very high speed power line communication (PLC) systems in the home environment. The development of such a technology is fundamental to realize the objective of reliably delivering new high speed services in the home environment in a network that integrates in a coordinated fashion also wireless systems. That is, an in-house network with the need...
