Talk by Dr.​ Shubha Sharma​​​ on "Hybrid Free Space optical (FSO)/Radio Frequency (RF) Communication for Future Wireless Networks"

Date : 18th Aug 2021 

Time: 4:00 PM

Online webinar

Free space optics (FSO) technology offers large bandwidth in the unlicensed spectrum that can support seamless high-speed broadband connectivity, which is a significant requirement for data intensive applications. However, the FSO link is highly susceptible to atmospheric effects.

A. Sharma, R. Kukreja, R. Prasad, S.D. Rao “DAGSurv: Directed Acyclic Graph Based Survival Analysis Using Deep Neural Networks” Asian Conference on Machine Learning, 2021.

In this work, we integrate the cause-effect relationship between covariates and the time-to-event outcome by encoding the causal directed acyclic graph structure into survival analysis.

G. Ghatak “Analysis of Multi-Hop Device-To-Device Networks with Half-Duplex Relays” National Conference on Communications (NCC), 2021.

In this paper, we analyze a multi-hop device-to-device (D2D) communication network operating in a region of cellular outage, e.g., in case of a natural disaster. In particular, we assume that the D2D devices operate in a half-duplex manner and can receive signals from or transmit to a single D2D relay. For this system, we characterize a multi-hop D2D transmission protocol wherein we divide the transmission area into multiple regions based on the D2D transmission range.

Neetu R.R, A. Gupta, G. Ghatak, A. Srivastava, V.A. Bohara “Joint Bandwidth and Position Optimization in UAV Networks Deployed for Disaster Scenarios” National Conference on Communications (NCC), 2021.

In this paper, we consider a disaster-affected area that has lost cellular connectivity. In such a scenario, we study a unmanned aerial vehicle (UAV) network deployed to restore the user connections to the core network. In particular, we propose a resource partitioning scheme for integrated access and backhaul in the downlink to sustain the user connections.

S.H. Gade, S. Deb “A Novel Hybrid Cache Coherence with Global Snooping for Many-core Architectures” ACM Transactions on Design Automation of Electronic Systems, 2021.

Cache coherence ensures correctness of cached data in multi-core processors. Traditional implementations of existing protocols make them unscalable for many core architectures. While snoopy coherence requires unscalable ordered networks, directory coherence is weighed down by high area and energy overheads. In this work, we propose Wireless-enabled Share-aware Hybrid (WiSH) to provide scalable coherence in many core processors.

News and Events

ECE Lab has organized a hardware design challenge, "Electrivire'21" conducted in two different stages on 13th September 2021 and 18th September 2021, subsequently.

Electrivire

The motivation of this event is to give you a chance to visit the campus, see the exciting labs equipped with a number of hardware resources, and have some hands-on experience. Moreover, there were plenty of prizes having worth of over 7000/- for the top 3 winners. The e-certificate is provided to all the registered participants.

PhD student from ECE was invited to speak at a symposium organized by United Nations Office of Outer Space Affairs.


Bushra Ansari, PHD student, recently talked about her research at the UN/Austria Symposium: “Space Applications for Food Systems” organised by the United Nations Office of Outer Space Affairs. The UN/Austria Symposium "Space Applications for Food Systems" took place online from 7 to 9 September, 2021. This year's key topic is how space technologies support food systems and thus contribute to activities around the UN Food Systems Summit convened by the UN Secretary General.

Dr. Pravesh Biyani

Dr. Pravesh Biyani has been awarded Prof. Rajeev Sanghal Faculty Fellowship in appreciation for his contributions towards the holistic development of students.
The fellowship was started by Prof. Ponnurangam Kumaraguru (Adjunct Faculty, IIITD) in 2020 and will be awarded each year to a faculty at IIIT-Delhi, having a wholesome impact on students.

A. Gupta, S. Saurabh "Implementing a Ternary Inverter Using Dual-Pocket Tunnel Field-Effect Transistors " is accepted in IEEE Transactions on Electron Devices.

In this article, we propose a standard ternary inverter (STI) based on a dual-pocket tunnel FET (DP-TFET) for low-power applications. Using 2-D device simulations, we demonstrate that if appropriate doping concentration and length are chosen for the dual-pocket, then the device can exhibit ternary inverter voltage transfer characteristics (VTCs) with three stable output voltage levels. Ternary inverter characteristics are obtained by two tunneling mechanisms in the device: 1) gate bias-independent within-channel tunneling and 2) gate bias-dependent source-channel tunneling. We also demonstrate that the ternary inverter obtained could be operated at different supply voltages by controlling the pocket doping concentration.
