Optimal Non-Coherent Detector for Ambient Backscatter Communication System
Sudarshan Guruacharya, Xiao Lu, Ekram Hossain
The probability density function (pdf) of the received signal of an ambient backscatter communication system is derived, assuming that on-off keying (OOK) is performed at the tag,…
Edge Caching for Cache Intensity under Probabilistic Delay Constraint
Tachporn Sanguanpuak, Sudarshan Guruacharya, Nandana Rajatheva +1
In order to reduce the latency of data delivery, one of techniques is to cache the popular contents at the base stations (BSs) i.e. edge caching. However, the technique of caching…
Approximation of Meta Distribution and Its Moments for Poisson Cellular Networks
Sudarshan Guruacharya, Ekram Hossain
The notion of meta distribution as the distribution of the conditional coverage probability (CCP) was introduced in \cite{Haenggi2015}. In this letter, we show how we can reconstru…
Edge Caching in Delay-Constrained Virtualized Cellular Networks: Analysis and Market
Tachporn Sanguanpuak, Sudarshan Guruacharya, Ekram Hossain +3
Caching of popular contents at cellular base stations, i.e., edge caching, in order to eliminate duplicate transmission through the backhaul can reduce the latency of data delivery…
Battery Recharge Time of a Stochastic Linear and Non-Linear Energy Harvesting System
Sudarshan Guruacharya, Vandana Mittal, Ekram Hossain
Systems harvesting energy from a stochastic source have been widely studied in the literature. However, we are not aware of any work that deals with the time it takes for a battery…
Self-Sustainability of Energy Harvesting Systems: Concept, Analysis, and Design
Sudarshan Guruacharya, Ekram Hossain
Ambient energy harvesting is touted as a low cost solution to prolong the life of low-powered devices, reduce the carbon footprint, and make the system self-sustainable. Most resea…
SINR Outage Evaluation in Cellular Networks: Saddle Point Approximation (SPA) Using Normal Inverse Gaussian (NIG) Distribution
Sudarshan Guruacharya, Hina Tabassum, Ekram Hossain
Signal-to-noise-plus-interference ratio (SINR) outage probability is among one of the key performance metrics of a wireless cellular network. In this paper, we propose a semi-analy…
Multi-Operator Spectrum Sharing for Small Cell Networks : A Matching Game Perspective
Tachporn Sanguanpuak, Sudarshan Guruacharya, Nandana Rajatheva +2
One of the many problems faced by current cellular network technology is the under utilization of the dedicated, licensed spectrum of network operators. An emerging paradigm to sol…
Analysis of SINR Outage in Large-Scale Cellular Networks Using Campbell's Theorem and Cumulant Generating Functions
Sudarshan Guruacharya, Hina Tabassum, Ekram Hossain
The signal-to-noise-plus-interference ratio (SINR) outage probability is one of the key performance parameters of a wireless cellular network, and its analytical as well as numeric…
Saddle Point Approximation for Outage Probability Using Cumulant Generating Functions
Sudarshan Guruacharya, Hina Tabassum, Ekram Hossain
This letter proposes the use of saddle point approximation (SPA) to evaluate the outage probability of wireless cellular networks. Unlike traditional numerical integration-based ap…
Integral Approximations for Coverage Probability
Sudarshan Guruacharya, Hina Tabassum, Ekram Hossain
This letter gives approximations to an integral appearing in the formula for downlink coverage probability of a typical user in Poisson point process (PPP) based stochastic geometr…
