OQAM implementation of GFDM

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).

FBMC-OQAM PAPR Reduction Schemes

2020 International Conference on Information and Communication Technology Convergence (ICTC), 2020
Peak 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

Receivers for VBLAST FBMC-OQAM Systems

IEEE Communications Letters, 2020
We 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 ...

FBMC/OQAM Transceiver for Ultralarge Bandwidths

2020 IEEE 5th International Symposium on Telecommunication Technologies (ISTT), 2020
We consider the problem of the downlink transceiver design when it needs to operate in an ultralarge analog bandwidth; more specifically, we propose to use the FBMC/OQAM system in a scenario where many other multicarrier transceivers are not able to operate.

Robust channel estimation for OFDM/OQAM

IEEE Communications Letters, 2009
When 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.

Capacity Analysis of FBMC-OQAM Systems

IEEE Communications Letters, 2017
This 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), 2018
Among 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

FBMC/OQAM Modulators with Half Complexity

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
The Filter Bank MultiCarrier (FMBC) concept can be seen as an extension of the Orthogonal Frequency Division Multiplex (OFDM) principle. Indeed, in the case where each sub-carrier uses an Offset Quadrature Amplitude Modulation (OQAM), we get with the FBMC/OQAM system a multicarrier modulation scheme with relaxed orthogonality constraints so that ...
