— 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 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)

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)
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)
Multi-Carrier Modulation (MCM) and especially Orthogonal Frequency Division Multiplexing (OFDM) are currently used in many radio transmission standards. Among these modulations, OFDM Offset QAM (OFDM/OQAM) is an interesting alternative to OFDM. However, differently to OFDM, OFDM/OQAM modulation cannot directly use Alamouti coding scheme due to the remaining(More)
