» Book by our faculty member Dr. Agnshul Majumdar, titled "Compressed sensing for Engineers" is out on stands. The book introduces the topic of compressed sending in a level accessible to engineering students. Reading it requires only a basic understanding of linear and optimization. The complex mathematical concepts are explained intuitively. The book mainly concentrates on algorithms and applications (in signal processing and machine learning). It contains Matlab implementation of almost all the algorithms discussed.
Compressed sensing (CS) studies the solution of a system of under-determined linear equations when the solution is known to be sparse. The subject revolutionised signal processing and machine learning since it's onset in late 2000s. CS paved way for faster MRIs and safer CT scans. It paved way for modern representation learning; CS concepts are being used today in sparse techniques for deep learning. This book introduces CS at the level accessible by professional engineers and does not expect an advanced mathematical background required for understanding other treatises on this topic. The emphasis is on algorithms and applications of compressed sensing.

» Paper titled "New Spectrum Efficient Reconfigurable Filtered-OFDM Based L-Band Digital Aeronautical Communication System" authored by Niharika Agrawal (Ph.D. Student, IIIT Delhi), Sumit Darak (Faculty, IIIT Delhi) and Faouzi Bader (Faculty, CentraleSupelec, France) has been accepted for publication in the journal IEEE Transactions on Aerospace and Electronic Systems.
To meet an ever-increasing demand of the spectrum for aeronautical communication, we propose new L-band digital aeronautical communication system (LDACS) using reconfigurable filtered OFDM (Ref-OFDM). The proposed protocol enables transceivers to dynamically adapt the transmission bandwidth over a wide range to meet the desired quality of service, and high out-of-band attenuation leads to significant improvement in the vacant spectrum utilization. We support our claims via theoretical analysis as well as simulation and complexity comparison results for various realistic channel conditions.

» Paper titled, "Distributed Learning and Optimal Assignment in Multiplayer Heterogeneous Networks" authored by H. Tibrewal (BTech student, IIT Bombay), S. Patchala (BTech student, IIT Bombay), M. Hanawal (Faculty IIT Bombay) and Sumit Darak (Faculty IIIT Delhi) has been accepted in IEEE INFOCOM 2019 (Core A* conference) scheduled for 29th April - 2nd May at Paris, France.
We consider an ad hoc network where multiple users access the same set of channels. The channel characteristics are unknown and could be different for each user (heterogeneous). No controller is available to coordinate channel selections by the users, and if multiple users select the same channel, they collide and none of them receives any rate (or reward). For such a completely decentralized network we develop learning algorithms that aim to achieve optimal network throughput. For the wideband sensing and narrowband sensing scenarios, we first develop explore-and-commit algorithms that converge to near-optimal allocation with high probability in a small number of rounds. Building on this, we develop an algorithm that gives logarithmic regret.
