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...
