Niladri Halder

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

Yashvanth (Graduate student member, IEEE) obtained his B.Tech (Honors) degree in Electronics and Communication Engineering and a minor degree in Computer Science and Engineering from NIT Trichy, India, in 2020. He is a recipient of the President’s Gold Medal of the institute in 2020 for achieving his best academic performance. He was also a recipient of the DAAD-WISE fellowship in 2019 and carried out a bachelor’s research internship in Germany during the summer of 2019. Currently, he is 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 intelligent reflecting surfaces for 6G and beyond wireless communications. His broad areas of research interests lie in signal processing and its applications to communication systems. He is a recipient of the Qualcomm Innovation Fellowship (QIF) in 2021 and 2022 and the Prime Minister’s Research Fellowship (PMRF), Govt. of India in 2022. He also won the Best Poster Presentation award for his work presented at the PMRF Symposium in 2024.

Research

My Primary interests lie in Statistical Signal Processing and Wireless Communication systems. My current research focus is on intelligent reflecting surfaces aided communication systems. Some of the problems on which I am working currently and have worked in the past include:

  1. Effect of IRS on Multiple Mobile Operators in Wireless Systems
  2. Intelligent Reflecting Surface (IRS) Assisted Opportunistic Communications
  3. Channel Estimation for IRS Assisted mmWave Massive MIMO Systems
  4. Phase Optimization for IRS-Assisted OFDM Systems
  5. Self Interference Cancellation in Full Duplex Wireless Communications
  6. Parameter Estimations in Bistatic MIMO Radar Systems using time-frequency analysis
