How to design efficient modems and networks for beyond-5G and 6G communications? How to provide reliable and secure communication systems in most challenging environments? Finally what principles must we follow to reach the limit of communication systems and what next? These are the kind of questions I want to pursue in my career. I firmly believe that one should always keep broadening his perspective as well as sharpen his skill set to keep up with the latest advancements. To this end, I am writing to apply for Purdue University, West Lafayette’s Graduate program in the Department of Electrical and Computer Engineering for specialization in Communications Networking Signal and Image Processing which would provide me with the necessary skills to help me excel in my current role as a Modem Systems Engineer in Qualcomm Research India. After securing 99. 9 percentile in JEE Advanced, one of India’s prestigious national level entrance examinations, I opted for Electronics and Electrical Communication Engineering(E&ECE) at the Indian Institute of Technology (IIT) Kharagpur - one of the best undergraduate programs in the country. The coursework at IIT Kharagpur introduced me to various areas such as Communication Theory, Electromagnetic Theory, Signal Processing, and VLSI circuits. The extensive lab work provided me an opportunity to practically implement a wide range of studies such as Analysis of Speech signals, Modulation schemes analysis, and comparison of MIMO receivers. These instilled in me a strong inclination towards wireless communication systems. I attained consistently good grades in the relevant courses such as Stochastic Processes, Linear Algebra, Signals and Systems, and Digital Communications. I attended the summer course organized by Dr. Mrigank Sharad, where I was further fascinated by the communication algorithms, particularly their mathematical models. To attain further expertise, I pursued Micro-Specialization in Embedded Wireless Systems offered by G. S. Sanyal School of Telecommunications, IIT Kharagpur. To get a flavour of practical implementation of Communication Theory and Networks, I have approached Dr. Debarati Sen to work on a project named “Disaster Communication Backbone Architecture(DiCoBA)”. Under her guidance, I have to develop a prototype for the backbone architecture with the help of multiple quadcopters and Raspberry Pis as a part of a team. We came up with our own algorithm where the quadcopters always stay in the range of each other and form a hopping network. Further analysis of the protocols to be used was performed and we could finally establish a successful hopping network among the quadcopters which work in a completely automated manner. This opportunity gave me massive learning experience in the field of wireless networks and introduced me to the skills which are required such as software development and automation. At the end of my pre-final year, I interned with the FPGA prototyping division at Mentor Graphics India where I enhanced their EDA tool to incorporate the clock tree debugger feature. I further created a lot of prototypes in the EDA tool which consists of various clock schemes to test the developed feature. During the course of the internship, I have learned pre-silicon modelling of systems and have mastered the skills required such as software product development and automation. These experiences helped me develop not only professionally but also individually. To further solidify my concepts in wireless communications and networks, I approached Prof. Raja Datta for my bachelor thesis project. Under his supervision, I have worked on an interesting problem called “Source Location Privacy in Wireless Sensor Networks”. I surveyed the existing algorithms and analysed the performance of these. I quantified the performance of the algorithms using statistical anonymity as a measure and provided a detailed comparison of them. Through this project, I have learned to apply the concepts of networks and mathematical analysis to a real world problem. As the next step in the project, I modelled one of the well performing algorithms “Fake Data Source Techniques” in NS-3 and Matlab. To gain more insight into the tools required for modelling and simulation, I attended a graduate level lab and successfully completed the assignments. This experience has made me intrigued in the usage of statistical analysis and stochastic processes to model real world problems and immensely motivated me to go towards research. This motivated me to complete courses such as Discrete Stochastic Process provided by MIT OCW to get a deeper understanding of the concepts involved in mathematical modelling. Following graduation, I joined Cisco Systems India as an Engineer with Wireless Division of Enterprise Networking led by Mr. Rajiv Koripalli. I have had the opportunity to work on Cisco’s efficient wireless solution to ease enterprise networking namely Elastic Wireless Lan Controller (eWLC). I developed a set of best practices for eWLC after extensive study of the experiments conducted and implemented a framework, a single click solution to set the required configuration on eWLC which also provides detailed analysis of each best practice. I also worked on verification of the latest feature Hotspot 2. 0/OpenRoaming in eWLC and also developed corresponding webUI to further ease the usage of the feature. Apart from those, I have been an integral part of development of Polaris, Cisco’s proprietary OS and provided support for multiple releases. Although working in Cisco has helped me to strengthen my wireless concepts, I felt that there has been no significant improvement in the research aspect. So I joined as a Modem Systems Engineer in Wireless Research Division of Qualcomm India. Currently, I am a part of RF Platform Interface(RFPI) systems team and working on the digital front-end transmitter of the upcoming Qualcomm next gen modem where the usual work revolves around deciding the algorithm to use based on extensive studies and simulating the HW. I firmly believe that expanding my knowledge in Wireless communications directly bears fruitful results in my work. So I decided to pursue graduate study in Communication and Signal Processing to broaden my skills and understand the concepts at a much advanced level. After extensively going through the courses and curriculum of MSECE online at Purdue University, West Lafayette, I firmly believe that the program offered by the ECE department will hone my skills and expand my knowledge. I wish to pursue Communications, Networking, Signal & Image processing(CNSIP) area and shape the coursework of my graduate studies on the lines of wireless communication, digital signal processing and their real-world applications such as massive MIMO, 5G, and emerging 6G technologies. The flexible curriculum here allows me to learn despite my full time job and family obligations. The eminent faculty members of ECE like Prof. Charles A Bouman and Prof. Mung Chiang and their vast research and teaching experience would provide me with an ideal environment for my development. I am also interested in a variety of courses offered by the school of Statistics. Further, I look forward to the chance to work with and learn from such distinguished people in the field. I have demonstrated my abilities and my enthusiasm to learn through my work in both academia and my industrial experience. I have been trying to push my boundaries from time to time to bring out my best. I think that this program offered by the university helps me achieve the same. I am confident that I will succeed as a graduate student and make a significant contribution. I look forward to being a part of this wonderful program offered by Purdue University, West Lafayette for an incredible and exciting experience.
