Millimeter-wave and Terahertz Spectrum for 6G Wireless
Shuchi Tripathi, Nithin V. Sabu, Abhishek K. Gupta +1
With the standardization of 5G, commercial millimeter wave (mmWave) communications has become a reality despite all the concerns about the unfavorable propagation characteristics o…
Coverage Analysis of Broadcast Networks with Users Having Heterogeneous Content/Advertisement Preferences
Kanchan Chaurasia, Reena Sahu, Abhishek Gupta
This work is focused on the system-level performance of a broadcast network. Since all transmitters in a broadcast network transmit the identical signal, received signals from mult…
Low-Complexity ZF/MMSE Receivers for MIMO-OTFS Systems With Imperfect CSI
Prem Singh, Abhishek Gupta, Himanshu B. Mishra +1
Orthogonal time-frequency space (OTFS) scheme, which transforms a time and frequency selective channel into an almost non-selective channel in the delay-Doppler domain, establishes…
Coverage Improvement of Wireless Sensor Networks via Spatial Profile Information
Kaushlendra Pandey, Abhishek Gupta
This paper considers a wireless sensor network deployed to sense an environment variable with a known spatial statistical profile. We propose to use the additional information of t…
On the Coverage Performance of Boolean-Poisson Cluster Models for Wireless Sensor Networks
Kaushlendra Pandey, Abhishek Gupta
In this paper, we consider wireless sensor networks (WSNs) with sensor nodes exhibiting clustering in their deployment. We model the coverage region of such WSNs by Boolean Poisson…
On Detection of Critical Events in a Finite Forest using Randomly Deployed Wireless Sensors
Kaushlendra K. Pandey, Abhishek K. Gupta
Ecosystem of a forest suffers from many adverse events such as wild-fire which can occur randomly anywhere in the forest and grows in size with time. This paper aims to analyze per…
Modeling Infrastructure Sharing in mmWave Networks with Shared Spectrum Licenses
Rebal Jurdi, Abhishek K. Gupta, Jeffrey G. Andrews +1
Competing cellular operators aggressively share infrastructure in many major US markets. If operators also were to share spectrum in next-generation millimeter-wave (mmWave) networ…
Macro diversity in Cellular Networks with Random Blockages
Abhishek K. Gupta, Jeffrey G. Andrews, Robert W. Heath
Blocking objects (blockages) between a transmitter and receiver cause wireless communication links to transition from line-of-sight (LOS) to non-line-of-sight (NLOS) propagation, w…
Modeling and Analyzing Millimeter Wave Cellular Systems
Jeffrey G. Andrews, Tianyang Bai, Mandar Kulkarni +3
We provide a comprehensive overview of mathematical models and analytical techniques for millimeter wave (mmWave) cellular systems. The two fundamental physical differences from co…
Gains of Restricted Secondary Licensing in Millimeter Wave Cellular Systems
Abhishek K. Gupta, Ahmed Alkhateeb, Jeffrey G. Andrews +1
Sharing the spectrum among multiple operators seems promising in millimeter wave (mmWave) systems. One explanation is the highly directional transmission in mmWave, which reduces t…
A Primer on Cellular Network Analysis Using Stochastic Geometry
Jeffrey G. Andrews, Abhishek K. Gupta, Harpreet S. Dhillon
This tutorial is intended as an accessible but rigorous first reference for someone interested in learning how to model and analyze cellular network performance using stochastic ge…
On the Feasibility of Sharing Spectrum Licenses in mmWave Cellular Systems
Abhishek K. Gupta, Jeffrey G. Andrews, Robert W. Heath
The highly directional and adaptive antennas used in mmWave communication open up the possibility of uncoordinated sharing of spectrum licenses between commercial cellular operator…
Are We Approaching the Fundamental Limits of Wireless Network Densification?
Jeffrey G. Andrews, Xinchen Zhang, Gregory D. Durgin +1
The single most important factor behind the data rate increases experienced by users of wireless networks over the past few decades has been densification, namely adding more base…
SINR and Throughput Scaling in Ultradense Urban Cellular Networks
Abhishek K. Gupta, Xinchen Zhang, Jeffrey G. Andrews
We consider a dense urban cellular network where the base stations (BSs) are stacked vertically as well as extending infinitely in the horizontal plane, resulting in a greater than…
Downlink Multi-Antenna Heterogeneous Cellular Network with Load Balancing
Abhishek K. Gupta, Harpreet S. Dhillon, Sriram Vishwanath +1
We model and analyze heterogeneous cellular networks with multiple antenna BSs (multi-antenna HetNets) with K classes or tiers of base stations (BSs), which may differ in terms of…
