Spectral Efficient Asymmetrically Clipped Hybrid FBMC for Visible Light Communication
International Journal of Optics, 2021 Filter bank multicarrier (FBMC) modulation has shown sufficient potential for wireless communication. A hybrid optical FBMC technique is proposed to improve the spectral efficiency of a visible light communication (VLC) system.

Continuous unconstrained PSO‐PTS strategy to maximize HPA energy efficiency for FBMC‐OQAM systems
IET Communications, 2023 In filter bank multi‐carrier (FBMC) with offset quadrature amplitude modulation (OQAM) systems, the major limitation of FBMC‐OQAM signaling is the high peak‐to‐average power ratio (PAPR).

Performance study of HF communication using NOMA over narrowband HF channel
IET Communications, Volume 17, Issue 14, Page 1683-1690, August 2023., 2023 The novelty of this research is to increase the bit rate on high frequency (HF) systems. Non‐orthogonal multiple access technique (NOMA) technology is used over HF at narrow band 3 kHz ranges. In order to have real experiments SDR Hack RF systems are used, and the results show improvement in bit rate up to 45%.

Joint radar communication system design based on filter bank multicarrier modulation scheme
IET Radar, Sonar &Navigation, Volume 17, Issue 1, Page 47-62, January 2023., 2023 Abstract Since orthogonal frequency division multiplexing (OFDM) signals are sensitive to Doppler shift, OFDM signals with cyclic prefix (CP) not only reduce the communication rate but also result in symmetric pseudo peaks in the ambiguity function of the radar, which eventually lead to the degradation of the performance of the joint radar ...

Journal of Electrical and Computer Engineering, Volume 2023, Issue 1, 2023., 2023 Nowadays, multicarrier modulation schemes are being widely used in wireless communication system than single‐carrier modulation techniques. Single‐carrier modulation schemes are less capable of dealing with multipath fading channels than multicarrier modulation schemes, which results in lower spectral efficiency.

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.

PAPR reduction technique for FBMC based visible light communication systems
IET Communications, Volume 16, Issue 15, Page 1807-1814, September 2022., 2022 Abstract One of the critical challenges in multicarrier‐based systems is peak to average power ratio (PAPR). Recently, Filter Bank Multicarrier (FBMC) is proved to be a promising candidate that can replace the traditional orthogonal multiplexing division (OFDM) scheme due to its better spectral efficiency, reducing both inter‐channel interference (ICI)

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