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…
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…
