FBMC/OQAM equalization: Exploiting the imaginary interference
2012 IEEE 23rd International Symposium on Personal, Indoor and Mobile Radio Communications - (PIMRC), 2012Filter bank based multicarrier (FBMC) modulations have recently gained a great interest. Indeed, when coupled with an Offset QAM (OQAM) coding on each sub-carrier, FBMC/OQAM can reach the maximum Nyquist rate and provide a compact spectrum. However, as with this modulation scheme no cyclic prefix is used, equalizers more efficient than a simple 1-tap ...

Synchronization Sequence Design for FBMC/OQAM Systems
IEEE Transactions on Wireless Communications, 2016In this paper, we propose a new sequence generation methodology to make a constant amplitude zero autocorrelation (CAZAC) preamble available in offset Quadrature Amplitude Modulation-based filter bank multicarrier (FBMC) synchronization. The role of the new sequence is to compensate the filtering and symbol overlap of the FBMC structure so as to ...

Use of Signals in Quadrature Over OFDM/OQAM
2007 IEEE 65th Vehicular Technology Conference - VTC2007-Spring, 2007Since more than one decade, orthogonal frequency division multiplexing (OFDM) has been widely selected for radio standards such as DVB-T or IEEE 802.11n. Thanks to the division of the overall stream over the sub-carriers multiplex, high rate transmissions over wide-band channels can be performed while still using a limited complexity receiver.

A unified framework for the construction of OFDM/OQAM systems
2005 12th IEEE International Conference on Electronics, Circuits and Systems, 2005OFDM/OQAM is a promising radio access technique for high data-rate fourth generation cellular systems, operating on time and frequency dispersive wireless channel. Contrary to the well established OFDM/QAM, it allows very well localized prototype waveforms to be used for critical unit-density time-frequency lattices, offering maximal spectrum ...
