A Discrete Bit Loading Algorithm for FBMC/OQAM [PDF]

open access: yesIEEE Signal Processing Letters, 2012
In this letter the discrete rate maximization problem is investigated for FBMC/OQAM. The analysis reveals that if there is crosstalk certain bit allocations violate the power constraints. Aiming at ensuring the feasibility along with alleviating the complexity we have devised a novel iterative algorithm, which always converges. Simulation-based results

Distortion analysis in OQAM/FBMC-based OFDMA [PDF]

open access: yes2015 IEEE 16th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2015
The paper considers an OFDMA scheme based on OQAM/FBMC and evaluates the interaction of the different users to one another under strong frequency selectivity or timing synchronization errors between users. More specifically, due to imperfect equalization, each user contributes to a distortion component in the received signal.

Peak-to-Average Power Ratio Reduction of FBMC/OQAM Signal Using a Joint Optimization Scheme

open access: yesIEEE Access, 2017
Owing to the signal structure difference between the filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) and the orthogonal frequency-division multiplexing (OFDM) systems, the existing technologies to reduce the peak-to ...

Joint Sparse Graph for FBMC/OQAM Systems [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2018
As an advanced non-orthogonal multiple access (NOMA) technique, the low density signature (LDS) has never been used in filter bank multicarrier (FBMC) systems. In this paper, we model a low density weight matrix (LDWM) to utilize the intrinsic interference in FBMC systems when single-tap equalization is employed, and propose a LDS-FBMC scheme which ...

Channel Estimation Based on IOTA Filter in OFDM/OQPSK and OFDM/OQAM Systems

open access: yesApplied Sciences, 2019
In this paper, we present a study of bit error rate (BER) for orthogonal frequency division multiplexing/offset quadrature phase shift keying (OFDM/OQPSK) and OFDM/offset quadrature amplitude modulation (OQAM) systems with an isotropic orthogonal ...

PAPR Reduction in the FBMC-OQAM System via Segment-Based Optimization

open access: yesIEEE Access, 2018
Multicarrier modulation (MCM) schemes have been intensively studied and developed, because of their numerous advantages, which include high data rate and immunity to multipath fading.

An Introduction to OFDM-OQAM

open access: yesCoRR, 2017
The Filter Bank MultiCarrier (FBMC) modulation with Offset QAM (OQAM), also know as OFDM-OQAM, has been very well studied in, roughly speaking, the last 15 years. A rich literature exists on the principle itself, discrete-time version and implementation, equalization, extension to MIMO, etc.

Advanced Chromatic Dispersion Compensation in Optical Fiber FBMC-OQAM Systems

open access: yesIEEE Photonics Journal, 2017
We report on several methods for the chromatic dispersion (CD) compensation in optical fiber offset-QAM-based filterbank multicarrier (FBMC-OQAM) systems.
