Optimal resource allocation in 5G system using modified lion algorithm

IET Communications, Volume 15, Issue 1, Page 126-141, 3 January 2021., 2021
Abstract This research work intends to examine the resource allocation issues within the hybrid multi‐carrier non‐orthogonal multiple access (MC‐NOMA) systems, which includes the NOMA and orthogonal multiple access (OMA) modes. This is exploited to attain the energy efficiency (EE) and spectral efficiency (SE) tradeoff with the minimum rate ...

Signal Modulation Identification Based on Deep Learning in FBMC/OQAM Systems

Mobile Information Systems, Volume 2021, Issue 1, 2021., 2021
Signal modulation identification (SMI) has always been one of hot issues in filter‐bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM), which is usually implemented by the machine learning‐based feature extraction. However, it is difficult for conventional methods to extract the signal feature, resulting in a limited probability ...

Channel Estimation Approach with Low Pilot Overhead in FBMC/OQAM Systems

Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021
In filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) systems, a large pilot overhead is required due to the existence of the imaginary interference. In this paper, we present an approach to reduce the pilot overhead of channel estimation. A part of pilot overhead is used for transmitting data, and compensating symbols are

Spectral Efficient Asymmetrically Clipped Hybrid FBMC for Visible Light Communication

International Journal of Optics, Volume 2021, Issue 1, 2021., 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. In this technique, a hybrid asymmetrically clipped optical offset quadrature amplitude modulation FBMC (HACO‐OQAM‐FBMC ...

FBMC system: an insight into doubly dispersive channel impact [PDF]

, 2016
It has been claimed that filter bank multicarrier (FBMC) systems suffer from negligible performance loss caused by moderate dispersive channels in the absence of guard time protection between symbols.

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.
