Cooperative relaying with energy harvesting relays : Asymptotic analysis using extreme value theory for non-identically distributed RVs.
Athira Subhash,Sheetal Kalyani +1 more
TL;DR: The utility of the asymptotic results for deciding the optimum TS and PS factors of the hybrid EH relays to minimize outage probability at the destination is presented and results from stochastic ordering can be utilized for simplifying the corresponding optimization problem.

Green DetNet: Computation and Memory efficient DetNet using Smart Compression and Training
TL;DR: In this paper, an incremental training framework for compressing popular Deep Neural Network (DNN) based on unfolded multiple-input-multiple-output (MIMO) detection algorithms like DetNet is introduced.
Journal ArticleDOI
Grafting Laplace and Gaussian distributions: A new noise mechanism for differential privacy
TL;DR: In this article , a new noise addition mechanism for differential privacy is introduced where the noise added is sampled from a hybrid density that resembles Laplace in the centre and Gaussian in the tail.

Adaptive link adaptation system and method
TL;DR: In this article, a method for modifying the MCS index for transmission using a computed offset is provided, where the offset is calculated based on HARQ feedback of transmissions, and a transition probability matrix with plurality of MCS indices is used for selecting the index based on the highest probability of transition.
