Power Allocation for Multi-Access Channel with Generalized Power Constraint
Prashant Narayanan, Lakshmi Narasimhan Theagarajan
We study the problem of decentralized power allocation in a multi-access channel (MAC) with non-cooperative users, additive noise of arbitrary distribution and a generalized power…
Deep Channel Prediction: A DNN Framework for Receiver Design in Time-Varying Fading Channels
Sandesh Rao Mattu, Lakshmi Narasimhan T, A. Chockalingam
In time-varying fading channels, channel coefficients are estimated using pilot symbols that are transmitted every coherence interval. For channels with high Doppler spread, the ra…
Group Testing for COVID-19: How to Stop Worrying and Test More
Lakshmi N. Theagarajan
The corona virus disease 2019 (COVID-19) caused by the novel corona virus has an exponential rate of infection. COVID-19 is particularly notorious as the onset of symptoms in infec…
Fusion of Correlated Decisions Using Regular Vine Copulas
Shan Zhang, Lakshmi Narasimhan Theagarajan, Sora Choi +1
In this paper, we propose a regular vine copula based methodology for the fusion of correlated decisions. Regular vine copula is an extremely flexible and powerful graphical model…
Large Player games on Wireless Networks
Prashant Narayanan, Lakshmi Narasimhan Theagarajan
We consider a scenario where users send packets to a common access point. The receiver decodes the message of each user by treating the other user's signals as noise. Associate…
Subspace-Aware Index Codes
Bhavya Kailkhura, Lakshmi Narasimhan Theagarajan, Pramod K. Varshney
In this paper, we generalize the well-known index coding problem to exploit the structure in the source-data to improve system throughput. In many applications, the data to be tran…
