Welcome! I am a (direct) Ph.D. student at the Dept. of ECE, Indian Institute of Science, Bengaluru, India. My advisor is Prof. Chandra R. Murthy. My current research focus is on beyond 5G/6G communications.
Biography
Niladri Halder (Graduate student member, IEEE) obtained his B.E. degree in Electrical Engineering from Jadavpur University, Kolkata, India, in 2021. He is currently pursuing his Ph.D. under the guidance of Prof. Chandra Murthy at the Dept. of ECE, IISc Bangalore, India, with a focus on the design and analysis of advanced modulation schemes for beyond 5G/6G. His broad areas of research interests lie in signal processing and its applications to communication systems. He is a recipient of the Prime Minister’s Research Fellowship (PMRF), Govt. of India in 2023.

Research
My Primary interests lie in Statistical Signal Processing and Wireless Communication systems. My current research focus is on waveform design for beyond 5G/6G. Some of the problems on which I am working currently and have worked in the past include:
- Delay-scale spread wideband channel estimation in underwater acoustic systems
- Variational Bayesian techniques for channel estimation and data detection
- Low complexity decoder design
