I am a Ph.D. student at the Dept. of ECE, Indian Institute of Science. My advisor is Prof. Chandra R. Murthy. My current research focus is on cell-free massive MIMO systems. Here is a short video about my research work. Here is the link to my new webpage Link.
I completed my M. Tech. in Communication Engineering from the Electronics and Electrical Engineering Department, Indian Institute of Technology, Guwahati. I obtained my B.Tech. in Electronics and Communication Engineering from Jalpaiguri Govt. Engineering College, West Bengal. My CV is available here. Google Scholar, ORCID, Linkedln
My research investigates fundamental physical layer design aspects of both cellular and cell-free massive MIMO communications. Some of the areas I am currently working on/worked in the past are:
