Graduate Research Assistant working under Professor Zhi Sun on Underwater MIMO communication.

Work discription:

• Proposed and developed a hybrid underwater distributed MIMO system using Acoustic antennas for beamforming and magnetic induction antennas for synchronization amongst the distributed transceivers.

• Compared carrier frequency and clock timing synchronization capabilities first numerically and then experimentally for a master-slave configuration.

• Performed numerical analysis on MATLAB for SNR, BER and Throughput for beamforming and space time coding using the proposed synchronization method.

• Validated the system using experiments for a transmit beamforming and Alamouti space time coding scheme in an in-lab water tank using Software-Defined Radios (USRP N210), Acoustic Hydrophones, Magnetic Induction antennas, GNU radio companion and MATLAB.

Airolyzr (Ecomappers) manufactures air and noise pollution measuring devices which can wirelessly sends live data to its website and mobile application.

My Contributions:

• Developed the Bluetooth low energy (BLE) based prototype and working model

• Worked with various microcontrollers like LinkitOne, Intel Edison, Arduino to design the project

• Calibrated the pollution sensors at The National Environmental Engineering Research Institute

• Procured funding and investment from Courage Digital Private Limited

• Led collaborations with K.J. Somaiya Hospital and K.J. Somaiya College of Science and Commerce for research purposes

• Executed deals and designed the products to be installed across Somaiya campus
