A new type of comb pilot in FBMC/OQAM
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018Scattered pilot-aided channel estimation in offset QAM-based filter bank multicarrier (FBMC/OQAM) systems has so far been only considered for slow fading channels. In more demanding scenarios, the classical auxiliary pilot (AP) idea has been shown to result a severe error.

Coordinated beamforming in MIMO FBMC/OQAM systems
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014In this contribution, we propose a coordinated transmit beamforming technique for point-to-point multiple-input-multiple-output (MIMO) filter bank based multi-carrier with offset quadrature amplitude modulation (FBMC/OQAM) systems. To enable reliable transmissions when the number of transmit antennas does not exceed the number of receive antennas and ...

Generalized Synchronization Algorithms for FBMC-OQAM Systems
IEEE Transactions on Vehicular Technology, 2018Synchronization is one of the critical issues for wireless communications. In this paper, we present low-complexity joint timing and carrier frequency offsets synchronization algorithms for filter-bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) systems by exploiting two uncorrelated consecutive real training symbols based on ...

On the Uplink Spectral Efficiency of the FBMC-OQAM Transceiver
2019 16th International Symposium on Wireless Communication Systems (ISWCS), 2019The analysis of the spectral efficiency that can be achieved by using the FBMC-OQAM transceiver in the uplink of the modern wireless networks is carried out. Such efficiency is studied in a scenario where the limitations are introduced by interferences due to the multiple access scenario, rather than by the presence of hostile wireless channels.

An efficient FTN implementation of the OFDM/OQAM system
2015 IEEE International Conference on Communications (ICC), 2015In this paper, we propose an implementation method for Orthogonal Frequency Division Multiplexing Offset Quadrature Amplitude Modulation (OFDM/OQAM) with Faster-Than-Nyquist (FTN) signaling. The proposed scheme can bring several advantages: 1) it approaches the theoretical rate gain of FTN signaling; 2) it can flexibly switch between Nyquist and FTN ...

Application of OQAM/OFDM Modulation in Troposcatter Communication
Proceedings of the Fifth International Conference on Network, Communication and Computing, 2016OFDM, as a efficient modulation, has been chosen to improve performance of the multipath fading channel in troposcatter communication. However the drawbacks of conventional OFDM, such as bad localization in time and frequency, spectrum efficiency reduction and power loss due to insertion of CP, are not easy to undervalue.

An Analysis of the EIC Method for OFDM/OQAM Systems
Journal of Communications, 2009OFDM/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.

Semiblind Channel Estimation for OFDM/OQAM Systems
IEEE Signal Processing Letters, 2015In this letter, we propose a semiblind channel estimation technique for OFDM/OQAM wireless systems. The proposed technique exploits the real property of transmitted symbols to blindly identify the channel-induced rotation in the received signal, thereby reducing the pilot overhead for estimation purpose.

An Efficient WOLA Structured OQAM-FBMC Transceiver
2018 Tenth International Conference on Ubiquitous and Future Networks (ICUFN), 2018In this paper, we evaluate and analyze performance of these systems with windowed overlap-add (WOLA) technique. The offset quadrature amplitude modulation - filter bank basis multi carrier (OQAM-FBMC) has been attracted. OQAM-FBMC was nominated as one of new waveforms for 5G communications due to its capability of frequency selectivity, cyclic prefix ...
