Advanced Chromatic Dispersion Compensation in Optical Fiber FBMC-OQAM Systems
We report on several methods for the chromatic dispersion (CD) compensation in optical fiber offset-QAM-based filterbank multicarrier (FBMC-OQAM) systems.

A margin adaptive scheduling algorithm for FBMC/OQAM systems [PDF]
This paper addresses the margin adaptive problem for the filter bank multicarrier (FBMC) modulation based on the offset QAM (OQAM), referred to as FBMC/OQAM. The analysis conducted in this paper reveals that due to the specific FBMC/OQAM transmission format the system has to deal with inter-user, inter-symbol and inter-carrier interference to solve the

Underwater acoustic (UWA) communication is the only option for underwater long-distance wireless communication. However, its data rate is very low, in tens of kbps, and the time-varying nature of the UWA channel exhibits a Doppler effect.

A suboptimal power allocation algorithm for FBMC/OQAM
This paper tackles the sum-rate maximization in FBMC systems. It is well-known that multipath fading destroys the orthogonality of the subcarriers, which brings a non-convex problem that can be interpreted as the maximization of a difference of concave functions.

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 ...

ALTERNATIVE LOW-COMPLEXITY APPROACHES FOR PAPR REDUCTION IN FBMC-OQAM SYSTEMS [PDF]
Recently, the Filter Bank Multi-Carrier with Offset-QAM modulation (FBMC-OQAM) system proved to be a strong candidate wave that can replace the conventional OFDM (Orthogonal Frequency Division Multiplexing) through several properties in future mobile ...

Receiver design for CDMA‐FBMC/ OQAM systems [PDF]
This Letter documents BER performance analysis of orthogonal affine precoder (OAP)‐based CDMA filter bank multi‐carrier offset QAM (CDMA‐FBMC/OQAM) systems. The use of OAP cancels the interference introduced by simultaneous transmission of data and training sequence during channel estimation and data detection.

This article proposes a hybrid SLM+PTS+RNN algorithm to mitigate the high PAPR challenge in UFMC systems for B5G networks. The method significantly improves power efficiency (by 30%–40%) while maintaining BER and PSD performance, outperforming traditional PAPR reduction techniques.

An Efficient Preamble Design Based on Comb-Type Pilots for Channel Estimation in FBMC/OQAM Systems
In this paper, we propose an efficient preamble design based on comb-type pilots (CTP) for channel estimation in filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) systems.
