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 multipath fading channels. Indeed, as it requires no guard interval, it has the advantage of a theoretically higher spectral efficiency. Furthermore if the pulse shape is well-localized in… (More)

This paper deals with the combination of OFDM/OQAM with the Alamouti scheme. After a brief presentation of the OFDM/OQAM modulation scheme, we introduce the fact that the well-known Alamouti decoding scheme cannot be simply applied to this modulation. Indeed, the Alamouti coding scheme requires a complex orthogonality property; whereas OFDM/OQAM only… (More)

We propose an alternative to the well-known multicarrier code-division multiple access (MC-CDMA) technique for downlink transmission by replacing the conventional cyclic-prefix orthogonal frequency division multiplexing (OFDM) modulation by an advanced filterbank-based multicarrier system (OFDM/OQAM). Indeed, on one hand, MC-CDMA has already proved its… (More)

This article deals with channel estimation (CE) in orthogonal frequency division multiplexing (OFDM)/OQAM. After a brief presentation of the OFDM/OQAM modulation scheme, we present the CE problem in OFDM/OQAM. Indeed, OFDM/OQAM only provides real orthogonality therefore the CE technique used in cyclic prefix-OFDM cannot be applied in OFDM/OQAM context.… (More)

Filter bank based multi-carrier (FBMC) is a multicarrier modulation scheme that can be considered as an alternative to conventional OFDM with cyclic prefix (CP-OFDM) for transmission over multi-path fading channels. Compared to CP-OFDM, FBMC can provide a higher information bit rate, since it operates without the addition of a CP. Furthermore, FBMC enables… (More)

OFDM/OQAM is a multi-carrier modulation scheme that, differently from conventional OFDM, does not require any guard interval. Indeed, the interference that results from a transmission over time and/or frequency selective channels can be partly contained if the pulse shape has been appropriately selected. Nevertheless, for certain transmission conditions, a… (More)
