Dual-Branch MRC Receivers under Spatial Interference Correlation and Nakagami Fading
Ralph Tanbourgi, Harpreet S. Dhillon, Jeffrey G. Andrews +1
Despite being ubiquitous in practice, the performance of maximal-ratio combining (MRC) in the presence of interference is not well understood. Because the interference received at…
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…
An Overview of Load Balancing in HetNets: Old Myths and Open Problems
Jeffrey G. Andrews, Sarabjot Singh, Qiaoyang Ye +2
Matching the demand for resources ("load") with the supply of resources ("capacity") is a basic problem occurring across many fields of engineering, logistics, and economics, and h…
Physical Layer Security in Downlink Multi-Antenna Cellular Networks
Giovanni Geraci, Harpreet S. Dhillon, Jeffrey G. Andrews +2
In this paper, we study physical layer security for the downlink of cellular networks, where the confidential messages transmitted to each mobile user can be eavesdropped by both (…
Fundamentals of Heterogeneous Cellular Networks with Energy Harvesting
Harpreet S. Dhillon, Ying Li, Pavan Nuggehalli +2
We develop a new tractable model for K-tier heterogeneous cellular networks (HetNets), where each base station (BS) is powered solely by a self-contained energy harvesting module.…
Effect of Spatial Interference Correlation on the Performance of Maximum Ratio Combining
Ralph Tanbourgi, Harpreet S. Dhillon, Jeffrey G. Andrews +1
While the performance of maximum ratio combining (MRC) is well understood for a single isolated link, the same is not true in the presence of interference, which is typically corre…
Fundamentals of Throughput Maximization with Random Arrivals for M2M Communications
Harpreet S. Dhillon, Howard C. Huang, Harish Viswanathan +1
For wireless systems in which randomly arriving devices attempt to transmit a fixed payload to a central receiver, we develop a framework to characterize the system throughput as a…
Downlink Rate Distribution in Heterogeneous Cellular Networks under Generalized Cell Selection
Harpreet S. Dhillon, Jeffrey G. Andrews
Considering both small-scale fading and long-term shadowing, we characterize the downlink rate distribution at a typical user equipment (UE) in a heterogeneous cellular network (He…
Power-Efficient System Design for Cellular-Based Machine-to-Machine Communications
Harpreet S. Dhillon, Howard C. Huang, Harish Viswanathan +1
The growing popularity of Machine-to-Machine (M2M) communications in cellular networks is driving the need to optimize networks based on the characteristics of M2M, which are signi…
Downlink MIMO HetNets: Modeling, Ordering Results and Performance Analysis
Harpreet S. Dhillon, Marios Kountouris, Jeffrey G. Andrews
We develop a general downlink model for multi-antenna heterogeneous cellular networks (HetNets), where base stations (BSs) across tiers may differ in terms of transmit power, targe…
