Data-aided synchronization for OFDM/OQAM systems
Signal Processing, 2012 The paper deals with the problem of preamble-based synchronization for OFDM/OQAM systems. Specifically, by exploiting the conjugate-symmetry property of a recently proposed preamble structure, a simple and robust procedure for timing and CFO synchronization is proposed.

Robust channel estimation for OFDM/OQAM
IEEE Communications Letters, 2009When orthogonal frequency division multiplexing offset-QAM (OFDM/OQAM), termed OQAM in short, was revealed to possess several advantages compared to OFDM, the channel estimation (CE) technique became a crucial issue for OQAM to make a practical sense.

2016 23rd International Conference on Telecommunications (ICT), 2016
Generalised frequency division multiplexing (GFDM) is one of the promising contenders for fifth generation (5G) wireless communications. It is of great interest as it shows a number of advantages over cyclic prefix orthogonal FDM (CP-OFDM). However, the non-orthogonality scheme of GFDM introduces intersymbol and intercarrier interference (ISI/ICI).

Receivers for VBLAST FBMC-OQAM Systems
IEEE Communications Letters, 2020We consider vertical Bell laboratories layered space-time architecture for offset quadrature amplitude modulation based filter bank multicarrier (FBMC) systems, and propose two different receivers. We first investigate a low-complexity QR decomposition (QRD) based conventional minimum mean square error (MMSE) successive interference cancellation (C ...

Preamble-based channel estimation in OFDM/OQAM systems: A review
Signal Processing, 2013 Filter bank-based multicarrier communications (FBMC) have recently attracted increased interest in both wired (e.g., xDSL, PLC) and wireless (e.g., cognitive radio) applications, due to their enhanced flexibility, higher spectral efficiency, and better ...

FBMC-OQAM PAPR Reduction Schemes
2020 International Conference on Information and Communication Technology Convergence (ICTC), 2020Peak to average power ratio (PAPR) is a major problem that affects the performance of multicarrier systems. Filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) is one of modulation schemes that has raised the attention of researchers given its superiority in terms of spectral efficiency. As any other multicarrier modulation

Capacity Analysis of FBMC-OQAM Systems
IEEE Communications Letters, 2017This letter presents a capacity analysis of filter bank multicarrier offset quadrature amplitude modulation (FBMC-OQAM) systems. In FBMC-OQAM receivers, it is common to preserve the real part of the demodulated signal samples for information recovery. The imaginary part of these samples, which are called intrinsic interference, is simply ignored.

Impacts of Phase Noise on CFBMC-OQAM
2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018Among many proposed multi-carrier systems, circular filter bank multi-carrier offset quadrature amplitude modulation (CFBMC-OQAM) is one of promising candidates for future wireless networks. This paper studies the impacts of the intrinsic interferences, namely inter-symbol interference (ISI) and inter-carrier interference (ICI), and phase noise (PN) on
