Dr. Prem Singh

IIIT Bangalore

Dr. Prem Singh received M. Tech and PhD degrees in Electrical Engineering from the Indian Institute of Technology Kanpur, India, in 2011 and 2020 respectively. His research interests lie in the area of parameter estimation and transceiver design for 5G and next-generation wireless technologies including Filter Bank Multicarrier (FBMC), Orthogonal Time-Frequency space (OTFS), massive MIMO and Millimeter-wave. His PhD thesis got selected for the final round (top two) for the Indian National Academy of Engineering (INAE) Innovative Student Project Award 2021 at the doctoral level. He received best PhD Thesis award in the 4th IEEE International Conference on Information and Communication Technology (CICT) 2020 organized by IIIT Kancheepuram, India. He worked as Project Executive Officer on the Indigenous 5G Testbed project, where he developed hardware and software algorithms for an end-to-end 3GPP compliant 5G-NR Testbed. His interests also lie in the area of designing practical 5G and beyond wireless systems using 3GPP standards. He is currently working as an Assistant Professor at International Institute of Information Technology (IIIT) Bangalore, India.


Dr. Ekant Sharma

IIT Roorkee

Dr. Ekant Sharma received the PhD and M.Tech. from IIT Kanpur, India, in May 2020 and May 2011 respectively, with the Signal Processing, Communication and Networks Group, in the department of Electrical Engineering. The main focus of his research is — design of signal processing algorithms for next generation wireless communication systems, that can provide multi-gigabit data rates and can improve energy consumption and spectrum utilization by orders of magnitude. Several key technologies have emerged in the recent past to make this vision feasible, including massive MIMO techniques, full-duplex cooperative wireless communication methods, intelligent reflecting surfaces, cell-free (cloud radio) networks and non-orthogonal multiple access technology. He had the opportunity to work on problems related to each of these areas. From 2011 to 2012, he was with IBM-Indian software lab and worked as an associate software engineer. From August 2019 to January 2021, he worked at 5G Testbed Lab, Indian Institute of Technology Kanpur where he designed base station hardware and software algorithms for 5G New Radio (NR) testbed. He is currently working as an Assistant Professor at the Indian Institute of Technology Roorkee. His Ph.D. thesis received an outstanding thesis award from Electrical engineering department IIT Kanpur and it was also chosen for the category: SPCOM Best Doctoral Dissertation—Honourable Mention at IEEE SPCOM conference. He has published 40+ papers in peer-reviewed Journals and Conferences and his research interests are within the areas of wireless communications systems, with a special focus on 5G and beyond wireless systems, energy efficiency, and optimization. He also regularly reviews papers for IEEE Journals, Transactions and Letters. He is currently a joint secretary in the executive committee of the IEEE Roorkee subsection.
