More learning with less labeling for face recognition
(Elsevier, 2023-05)
In this paper, we propose an improved face recognition framework where the training is started with a small set of human annotated face images and then new images are incorporated into the training set with minimum human ...
Model-predictive control of multilevel inverters: challenges, recent advances, and trends
(IEEE, 2023-09)
Model-predictive control (MPC) has emerged as a promising control method in power electronics, particularly for multiobjective control problems such as multilevel inverter (MLI) applications. Over the past two decades, ...
Joint lifetime-outage optimization in relay-enabled IoT networks—A deep reinforcement learning approach
(IEEE, 2023-01)
Network lifetime maximization in Internet of things (IoT) is of paramount importance to ensure uninterrupted data transmission and reduce the frequency of battery replacement. This letter deals with the joint lifetime-outage ...
Characterization of orbital angular momentum-multiplexed FSO channel in the presence of pointing errors
(IEEE, 2023)
Free space optical communication (FSO) uses laser transmitters at near-infrared wavelengths for line-of-sight wireless communication. Through the use of advanced laser beams instead of the conventional Gaussian-shaped beam, ...
Pilot-aided channel estimation for RIS-assisted wireless systems over time-varying fading channels
(IEEE, 2023)
Reconfigurable intelligent surfaces (RISs) have emerged as a promising technology for improving wireless communication system performance. RISs can adjust signals' phase and amplitude, resulting in improved signal strength. ...
FSO-based backhauling for airborne THz base stations
(IEEE, 2023)
Airborne nodes in the form of high-altitude platform stations (HAPSs) or unmanned aerial vehicles (UAVs) can be used for backhauling and wireless access. In this paper, we investigate the cascaded free space optical ...
Experimental demonstration of an FPGA-based outdoor VLC broadcasting system
(IEEE, 2023)
Visible light communication (VLC) uses light-emitting diodes (LEDs) to transmit data by turning them on and off at very high speeds, too fast for the human eye to perceive. In outdoor environments, LED-based streetlights ...
Soft actor-critic-based computation offloading in multiuser MEC-enabled IoT-A lifetime maximization perspective
(IEEE, 2023-10-15)
This article studies the network lifetime optimization problem in a multiuser mobile-edge computing (MEC)-enabled Internet of Things (IoT) system comprising an access point (AP), a MEC server, and a set of K mobile devices ...
An efficient algorithm for disparity map compression based on spatial correlations and its low-cost hardware architecture
(Elsevier, 2023-11)
This paper proposes a low-cost disparity map compression algorithm and its hardware architecture for high resolution and high frame rate applications. The proposed algorithm uses spatial correlations between neighboring ...
Vehicular visible light communication with low beam transmitters in the presence of vertical oscillation
(IEEE, 2023-08)
The availability of light-emitting diodes (LEDs) in vehicle exteriors makes possible the use of visible light communication (VLC) as a vehicle-to-vehicle (V2V) wireless connectivity solution. While there has been a growing ...
