Shibsankar's Experiences:
From August 2021 to Present, Post Doctoral Fellow advised by Prof. Adrish Banerjee and Prof. Abhay Karandikar, IIT Kanpur, India
From January 2021 to July 2021, Senior Project Scientist advised by Prof. Adrish Banerjee, IIT Kanpur, India.
From August 2015 to November 2020, Research Scholar in the Department of Mathematics, Indian Institute of Technology Patna, Bihar, India.
November 2020, PhD awarded in the Department of Mathematics, Indian Institute of Technology Patna. Thesis title: ``Efficient Design of Complementary Sequences from Matrices of Polynomials" advised by Prof. Sudhan Majhi, IIT Patna, India. The contributions of this research are arranged into the following stages:
An efficient multiplier-free implementation of the generator based on multiplexers and read-only memories (ROMs) in the design of CCCs and a compact notation for CCC with various lengths, which settle an open problem on the connection between a para-unitary (PU) matrix and CCC.
A certain restriction on the expanded forms of the PU matrices to enable precise computation of the periodic correlation functions of the constructed sequences in the design of near-optimal ZCZ sequence sets.
A compact notation in treating matrix representations of optimal ZCCSs with more flexible parameters compared to the previous techniques by introducing a novel idea of Z-para-unitary (ZPU) matrices. ZPU matrix has an advantage over the conventional PU matrix with regard to the availability of wider range of set sizes and sequence lengths
