Welcome!

I am a Professor in the department of Electrical Communication Engineering at the Indian Institute of Science, Bangalore, India. My research interests are primarily in the areas of digital signal processing, information theory, estimation theory, and their applications in the optimization of wireless communication systems.

• [09 Dec. 2020]: Two of our tutorial proposals were accepted for presentation at ICASSP 2021 (presenter names in alphabetical order):
  • Signal Processing for Mass Testing in Fighting a Pandemic: A Sampling Theory Perspective by Chandra R. Murthy, Ajit Rajwade, Jonathan Scarlett and Weiyu Xu, and
  • Practical Massive MIMO: Performance Bottlenecks and How to Overcome Them by Ribhu Chopra, Erik G. Larsson, Chandra R. Murthy, and Himal A. Suraweera.
• [11 Nov. 2020]: Our submission titled “Learned Chester” to the ITU AI/ML in 5G Challenge on site specific-channel estimation with hybrid mmWave MIMO systems ITU-ML5G-PS-025 won the 3rd place! This was joint work between Sai Thoota, Sameera Bharadwaja and Chandra Murthy at the Dept. of ECE, IISc Bangalore, and Rakesh Mundlamuri, Christo Thomas and Marios Kountouris at Eurecom, France. Here is the slack announcement. Here is a short description of our solution video,pdf. This solution won the “popular vote” in the grand final!” Thank you to all those who supported us!

“I started with the purely tentative hypothesis that the person who signed the will was not Jeffrey Blackmore. I assumed this; and I may as that I did not believe it at the time, but merely adopted it as a proposition that was worth testing. I accordingly tested it, 'Yes?' Or 'No?' With each new fact; but as each new fact said 'Yes,' and no fact said definitely 'No,' it's probability increased rapidly by a sort of geometrical progression. The probabilities multiplied into one another. It is a perfectly sound method, for one knows that if a hypothesis is true, it will lead one, sooner or later, to a crucial fact by which its truth can be demonstrated.” R. Austin Freeman, "The Mystery of 31 New Inn".
