Hobbies and For Fun

To take a break from my daily routine and activities, I play the guitar and make music for fun. You can check out my creations here.

Tata Makerthon Challenge-Techfest, IIT Bombay

Built an autonomous real-time system with a 3-axis object tracking gimbal system to search the surroundings for an object in an image provided by a smartphone. Implemented using Raspberry Pi, Arduino and a USB-webcam. A video of the working prototype can be found here.

Inter IIT Tech Meet

I was part of the contingent representing IIT Madras in two events at the Inter IIT Tech Meet in IIT Roorkee. The first event was Ashoka Tech for Social Change – my team presented a technology for aggregation of local scrap collectors, for which we won the bronze medal. The second event was a hackathon – my team designed a system for effective crowdsourcing of user information/complaints about public spaces, for which we won the gold medal.

Runners up - Flipkart Grid 2.0

A national level competition, where we built an end-to-end system for digitisation of invoices using digital image processing and OCR.

Convergence of EM Algorithm for Gaussian Mixtures with Unbalanced Mixing

Researched faster algorithm (DAEM) for GMMs with unbalanced mixing coefficients. Applied method to approximate non-Gaussian (𝛼-stable) noise models and use method for wireless channel estimation. This project was done under the guidance of Prof. Sheetal Kalyani.

Compressed Sensing for De-noising Audio Signals

Applied Compressed Sensing (CS) Techniques to get a sparse approximation of an audio signal in the frequency domain for denoising by posing it as an L1 convex optimization problem. Done under the guidance of Prof. Rachel K, for the course EE5121 – Convex Optimization.

Phase-Locked Loop System and Circuit Design for Clock generation

Designed a complete PLL system for 2.56GHz clock generation at transistor level. Simulated and optimized performance of PLL for key metrics like spur rejection, power supply rejection, phase noise with nominal loop gain and phase margin. This project was done under the guidance of Prof. Saurabh Saxena, for the course EE6324 – Phase Locked Loops.

Presentation on Proof of Polar Codes

In this presentation, I give an intuitive understanding to polar codes and explain the mechanics of the proof of their working using Martingale techniques and concentration inequalities. This project was done under the guidance of Prof. Abhishek Sinha, for the course EE6112 – Topics on Random Processes and Concentration Inequalities.

Blind Estimation of Communication Link Parameters and Signal Separation of Co- Frequency Signals in Wireless Communication.

I completed my Master’s Thesis under the guidance of Prof. Devendra Jalihal and also the mentorship of Prof. Radhakrishna Ganti at IITM.
