Interference-free SDMA for FBMC-OQAM [PDF]
EURASIP Journal on Advances in Signal Processing, 2013 Filter-bank multi-carrier (FBMC) modulations have recently been considered for the emerging wireless communication systems as a means to improve the utilization of the physical resources and the robustness to channel time variations. FBMC divides the overall frequency channel in a set of subchannels of bandwidth proportionally decreasing with the ...

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 ...

Distortion analysis in OQAM/FBMC-based OFDMA [PDF]
2015 IEEE 16th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2015 The paper considers an OFDMA scheme based on OQAM/FBMC and evaluates the interaction of the different users to one another under strong frequency selectivity or timing synchronization errors between users. More specifically, due to imperfect equalization, each user contributes to a distortion component in the received signal.

Widely linear filtering in modern MIMO transceivers [PDF]
, 2009 This thesis deals with the multiple-input multiple-output (MIMO) equalization with widely linear (WL) filtering. The WL filtering outperforms the linear one in presence of rotationally variant signals, with no significant complexity increase. It has been
