Maximum Spectral Efficiency With Adaptive MQAM Transmissions Over Terrestrial Coherent FSO Links
Himani Verma, Kamal Singh, Ranjan K. Mallik
Coherent free-space optical (FSO) communication is recognized as a key enabler for ultra-high-capacity fronthaul and backhaul links in next-generation wireless networks. Spectrally…
Maximum Spectral Efficiency of Adaptive Coherent Terrestrial FSO Links
Himani Verma, Kamal Singh, Ranjan K. Mallik
Terrestrial free-space optical (FSO) communication systems, while designed to operate on large unlicensed optical bandwidths, are fundamentally power-constrained due to stringent e…
An Efficient Ratio Detector for Ambient Backscatter Communication
Wenjing Liu, Shanpu Shen, Danny H. K. Tsang +2
Ambient backscatter communication (AmBC) leverages the existing ambient radio frequency (RF) environment to implement communication with battery-free devices. One critical challeng…
Channel Estimation and Secret Key Rate Analysis of MIMO Terahertz Quantum Key Distribution
Neel Kanth Kundu, Soumya P. Dash, Matthew R. McKay +1
We study the secret key rate (SKR) of a multiple-input multiple-output (MIMO) continuous variable quantum key distribution (CVQKD) system operating at terahertz (THz) frequencies,…
Machine Learning Based Parameter Estimation of Gaussian Quantum States
Neel Kanth Kundu, Matthew R. McKay, Ranjan K. Mallik
We propose a machine learning framework for parameter estimation of single mode Gaussian quantum states. Under a Bayesian framework, our approach estimates parameters of suitable p…
MIMO Terahertz Quantum Key Distribution
Neel Kanth Kundu, Soumya P. Dash, Matthew R. McKay +1
We propose a multiple-input multiple-output (MIMO) quantum key distribution (QKD) scheme for terahertz (THz) frequency applications operating at room temperature. Motivated by clas…
Incremental Relaying for Power Line Communication: Performance Analysis and Power Allocation

In this paper, incremental decode-and-forward (IDF) and incremental selective decode-and-forward (ISDF) relaying are proposed to improve the spectral efficiency of power line commu…
RACH in Self-Powered NB-IoT Networks: Energy Availability and Performance Evaluation
Yan Liu, Yansha Deng, Maged Elkashlan +3
NarrowBand-Internet of Things (NB-IoT) is a new 3GPP radio access technology designed to provide better coverage for a massive number of low-throughput low-cost devices in delay-to…
Incremental selective decode-and-forward relaying for power line communication
A. Dubey, C. Kundu, T. M. N. Ngatched +2
In this paper, an incremental selective decode-and-forward (ISDF) relay strategy is proposed for power line communication (PLC) systems to improve the spectral efficiency. Traditio…
Physical Layer Security in Three-Tier Wireless Sensor Networks: A Stochastic Geometry Approach
Yansha Deng, Lifeng Wang, Maged Elkashlan +2
This paper develops a tractable framework for exploiting the potential benefits of physical layer security in three-tier wireless sensor networks using stochastic geometry. In such…
Power Allocation for Conventional and Buffer-Aided Link Adaptive Relaying Systems with Energy Harvesting Nodes
Imtiaz Ahmed, Aissa Ikhlef, Robert Schober +1
Energy harvesting (EH) nodes can play an important role in cooperative communication systems which do not have a continuous power supply. In this paper, we consider the optimizatio…
