Meaning: Wisdom lies in keeping it simple for your audience, and grasping all intricacies when others speak.

I am a Doctoral Research Scholar with the Communications, Signal Processing, and Communication Networks group (EE1) of Electrical Engineering Department at IIT-Madras. I work under the guidance of Prof.K.Giridhar on many aspects of Signal Processing for Wireless Communication. I am pursuing my doctoral research under INSPIRE FELLOWSHIP provided by DST, Government of India.

Education Background

• B.Tech in ECE from Sree Vidyanikethan Engineering College, Tirupati in 2011.
• M.Tech in Communication Systems from SASTRA University Thanjavur in 2016.
• Summer Research Fellowship from the Indian Academy of Sciences at IIT-Ropar under the guidance of Dr.Rajesh V.Nair in 2015.
• Master's thesis work was done as an intern at IIIT-Hyderabad under the guidance of Dr.Sachin Chaudhary.

Research Interests

• Signal Processing for Wireless Communication
• Waveform designs for Tactical Communication
• Sparse Signal Recovery
• Array Signal Processing

Research Topic

I am working on Frequency Projection topic to exploit the frequency-dependent correlation between different frequency bands for next-generation wireless communication.The primary motivation here is for next-generation wireless communication; an overlay network may be deployed in conjunction with the existing underlay network. The key idea is to use the knowledge obtained from a lower frequency network to coarse estimate the useful parameters for the operation of a higher frequency network. It reduces the overhead caused by direct evaluation. For example, in a higher frequency network, the cost required for link establishment and operation can be minimized by using prior information obtained from a lower frequency network. This also reduces the hardware constraints of the overlay network, which in turn implements next-generation wireless communication cost-efficient.
