Welcome to my professional profile! I am currently serving as an Assistant Professor in the Department of Electrical Engineering at Indian Institute of Technology, Tirupati, a position I have held since July 2023. Prior to this, I contributed to the academic community as an Assistant Professor in the Department of Electronics and Electrical Engineering at the Indian Institute of Technology, Guwahati, from January 2022 to June 2023.

My academic journey includes a pivotal phase as a post-doctoral researcher collaborating with Professor Erik G. Larsson at Linkoping University in 2021. I successfully earned my Ph.D. in 2020 from the Department of Electrical Communication Engineering at the Indian Institute of Science, Bangalore, under the guidance of Prof. Neelesh B. Mehta. Before delving into academia, I honed my skills in industry as a design engineer from July 2012 to July 2016, contributing to the LTE and WiFi teams at Broadcom Communications, Bangalore.

My research endeavors span various facets of wireless communication, focusing on low-complexity multiple antenna techniques, spectrum sharing strategies, next-generation wireless standards, cell-free Massive MIMO, machine learning applications in wireless communications, and the innovative realm of Intelligent Reflecting Surfaces. I am passionate about exploring and advancing the frontier of wireless technology.

Thesis title: Transmit Antenna Selection in Underlay Spectrum Sharing: Roleof Power Adaptation, Interference Constraint, and Channel State Information.

In this thesis, we study the role of power adaptation, interference constraint, and channel state information on the optimal antenna selection at an underlay secondary transmitter.

1. With binary on-off power adaptation:

  • We first developed a novel and symbol error probability optimal antenna selection rule in the presence of a single primary receiver.
  • We then extended it to the multiple primary receivers scenario with partial channel state information.

2. With continuous power adaptation:

  • We first developed a new optimal joint antenna selection and power adaptation rule with instantaneous channel information.
  • We then developed an optimal antenna selection rule with statistical channel information. Here, we showed that the optimal antenna to select is independent of the interference constraint.

In all the above cases, we achieved a one to two orders of magnitude reduction in the symbol error probability over existing ad hoc selection algorithms.
