ViLDAR: a novel speed estimation system using visible light in vehicles
(IEEE, 2017)
In this paper, we introduce Visible Light Detection and Ranging (ViLDAR): a novel speed estimation system that utilizes visible light variation during a known time difference. The use of light emitting diodes (LED) in ...
Deep Q-learning based optimization of VLC systems with dynamic time-division multiplexing
(IEEE, 2020)
The traditional method to solve nondeterministic-polynomial-time (NP)-hard optimization problems is to apply meta-heuristic algorithms. In contrast, Deep Q Learning (DQL) uses memory of experience and deep neural network ...
Fast-decodable MIMO HARQ systems
(IEEE, 2015-05)
This paper presents a comprehensive study on the problem of decoding complexity in a Multi-Input Multi-Output (MIMO) Hybrid Automatic Repeat reQuest (HARQ) system based on Space-Time Block Codes (STBCs). We show that there ...
Auction based spectrum trading for cognitive radio networks
(IEEE, 2013-06)
In this letter, we consider the shared used model in cognitive radio networks and design a spectrum trading method to maximize the total satisfaction of the Secondary Users (SUs) and revenue of the Wireless Service Provider ...
Performance of multiuser scheduling in free space optical systems over atmospheric turbulence channels
(IEEE, 2015-10)
In this study, the authors consider a multiuser multiple-input multiple-output (MU-MIMO) free space optical (FSO) communication system and investigate the performance of various scheduling protocols which provide different ...
Infrastructure-to-vehicle cooperative communications with decode-and-forward relaying
(IEEE, 2011)
In this paper, we consider infrastructure-to-vehicle cooperative communications in which roadside access points use vehicles as relaying terminals. This can be particularly useful in suburban or remote areas where the ...
Relay-assisted OFDM-based visible light communications over multipath channels
(IEEE, 2015-07)
In this paper, we investigate the performance of relay-assisted visible light communication (VLC) system over multipath channels. We consider an indoor environment where the ceiling light serves as the information source ...
A new control plane for 5G network architecture with a case study on unified handoff, mobility, and routing management
(IEEE, 2014-11)
The tremendous growth in wireless Internet use is showing no signs of slowing down. Existing cellular networks are starting to be insufficient in meeting this demand, in part due to their inflexible and expensive equipment ...
Hardware division by small integer constants
(IEEE, 2017-12)
This article studies the design of custom circuits for division by a small positive constant. Such circuits can be useful for specific FPGA and ASIC applications. The first problem studied is the Euclidean division of an ...
Error-rate performance analysis of cooperative OFDMA system with decode-and-forward relaying
(IEEE, 2014-06)
In this paper, we investigate the performance of a cooperative orthogonal frequency-division multiple-access (OFDMA) system with decode-and-forward (DaF) relaying. Specifically, we derive a closed-form approximate ...
