Synchronization Algorithms for FBMC Systems [PDF]
, 2009 Filter bank multicarrier (FBMC) systems, such as FMT and OFDM/OQAM systems, can provide reduced sensitivity to narrowband interference, high flexibility to allocate group of subchannels to different users and a high spectral containment. On the other hand, as all the multicarrier modulation schemes, one of their major drawbacks is their sensitivity to ...

Design and Convergence Analysis of an IIC-Based BICM-ID Receiver for FBMC-QAM Systems
IEEE Open Journal of the Communications Society, 2020 Next generation cellular networks are expected to connect billions of devices through its massive machine-type communication (mMTC) use case. To achieve this, waveforms with improved spectral confinement and high spectral efficiency compared to cyclic ...

Real-Valued Orthogonal Sequences for Iterative Channel Estimation in MIMO-FBMC Systems
IEEE Access, 2019 In this paper, we present a novel sequence design for efficient channel estimation in multiple input multiple output filterbank multicarrier (MIMO-FBMC) system with offset QAM modulation. Our proposed sequences, transmitted over one FBMC/OQAM symbol, are

Evaluation and Analysis of FBMC/OQAM Systems Based on Pulse Shaping Filters
IEEE Access, 2020 Cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) is the most widespread multicarrier modulation scheme. However, the use of a rectangular filter in CP-OFDM causes poor out-of-band (OoB) radiation.

Hyperbolic FRFT‐FBMC for 5G signals [PDF]
IET Communications, 2019 This study considers a novel type of signal for 5G communications based on filter bank multi‐carrier‐quadrature amplitude modulation (FBMC‐QAM). In this new method, the innovative type of fractional Fourier transform on the basis of hyperbolic chirps that denominated as hyperbolic fractional Fourier transform (FRFT) is implemented.

First‐Principles Study of Edge and Pore Stability in O‐Terminated Titanium Carbide MXenes
Small Structures, Volume 7, Issue 3, March 2026.This study shows how in‐plane pores shape the structure and electronics of Ti3C2O2 MXenes. Oxygen coordination stabilises edges and pore walls, while larger pores mimic edge chemistry without losing metallic behaviour. Undercoordinated sites attract chemical terminations, offering a clear design principle for creating stable, reactive, and conductive ...

Capacity analysis of WCC-FBMC/OQAM systems [PDF]
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016 This paper evaluates the capacity of weighted circularly convolved FBMC/OQAM systems. A rigorous mathematical model is derived to calculate the increase of capacity that can be obtained thanks to the lattice structure of the modulation and the exploitation of the intrinsic interference.

Decoding Schemes for FBMC with Single-Delay STTC
EURASIP Journal on Advances in Signal Processing, 2010 Orthogonally multiplexed Quadrature Amplitude Modulation (OQAM) with Filter-Bank-based MultiCarrier modulation (FBMC) is a multicarrier modulation scheme that can be considered an alternative to the conventional orthogonal frequency division multiplexing
