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.

Power Allocation and Capacity Analysis for FBMC-OQAM With Superimposed Training

open access: yesIEEE Access, 2019
Superimposed training (ST) is a semiblind channel estimation technique, proposed for orthogonal frequency division multiplexing (OFDM), where training sequences are added to data symbols, avoiding the use of dedicated pilot-subcarriers, and increasing ...

Joint Active User Detection, Timing Offset and Channel Estimation for FBMC‐Based Uplink Massive Access Systems

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
The robustness against timing offsets of filter bank multi‐carrier (FBMC) is appealing for grant‐free massive access scenarios that mainly adopt asynchronous transmissions. In this work, we propose a compressed sensing based algorithm for joint active user detection as well as timing offset and channel estimation in uplink communication under the ...
