    About Me

    Digital Systems engineer with a demonstrated history of working in research and academic institutes. Prime experience in simulating and implementing signal processing algorithms on FPGA, particularly for radio astronomy instrumentation.

    Research/Working Experience

    Institute name:Giant Metrewave Radio Telescope(GMRT), NCRA-TIFR

    Duration: Feb. 2019 –Present

    Project Goal: Development of narrow-band multi-beam beamformer for Focal Plane Array

    • Developed optimized architecture for multi-element, multi-beam beamformer us- ing FPGA re-configurability. Designed a 32-input, 5-beam, 1024 spectral channel beamformer on a single Virtex-5 FPGA. • Implemented a narrow-band beamformer and correlator on ROACH-1 (Virtex-5 FPGA) platform. Xilinx System Generator ® tool used for design implementation.

    • Beamformer functionality i.e electronic beamsteering using phased array tech- niques tested in free space test range. Involved system level simulation using MATLAB, analysis of RF and base-band processing system and ADC characteri- zation. • Implemented and tested optimal beamforming algorithm with an L-band Focal Plane Array in aperture array mode to achieve optimum SNR.

    • Basic experiments on null-steering and multi-beamforming

    • Currently working on wideband beamformer implementation on Xilinx RF System on Chip (RFSoC)

    Institute name:Indian Institute of Technology Indore (IIT,Indore)

    Project Goal: L and C band interferometer design for galaxy cluster observation pathfinder

    • Involved in digital design and receiver chain testing. Designed FPGA-based four-element correlator using model-based approach through Xilinx System Generator and CASPER (collaboration for astronomical signal processing and electronics research) toolflow.
    • Design tested with L-band analog receiver chain. Testing involved L-band analog chain characterization and real time sky signal testing
    • Analyzed astronomical data from Ooty Radio Telescope using python and MATLAB.
    • Lab demonstration of interferometer (correlator) using Software Defined Radio(RTSDR) for students.

    Institute name:Giant Metrewave Radio Telescope(GMRT), NCRA-TIFR

    Duration: Aug. 2016 –March 2017

    Project Goal:Design,Implementation and Testing of FPA Wideband Beamformer Prototype.

    • The work involved simulation, design, implementation and testing of FPGA-based wideband beamformer for Focal Plane Array.
    • Designed free-space test range for testing the beamformer and correlator.
    • Characterization of RF to IF converter unit.
    • Working with RF and analog test instruments for system-level testing of beam-former.
