INDIAN WIRELESS WIZARD-PROFESSOR AROGYASWAMI PAULRAJ.

 

Have you ever heard of Professor Arogyaswamy Paulraj? 

I never heard of him till yesterday when a Whats App post was made on him  in my classmates group and what I read about the guy amazed me.

He is an Engineer from a place called Pollachi in Tamilnadu and joined the Indian Navy as a Cadet in 1961 at NDA Khadakvasla and was commissioned in 1965.

He was deputed to IIT Delhi between 1969-71 for doing his masters, instead he directly transitioned into his PhD and completed it in 1973.From 1972 to 74 he led a team at IIT Delhi to redesign the British developed Anti Submarine Sonar to be fitted on our Navy warships when no country was ready to pass on that technology to us.

From 1987 to 1989 he supervised the development of a large systems software suite for parallel computers at the Centre for Development of Advanced Computing, Bangalore and concurrently supervised the development of Radar and communications systems at Bharat Electronic cs.

He was the founding Director of the center for Artificial Intelligence and Robotics, Bangalore, and the Center for Development of Advanced Computing Bangalore .

And he was doing all that when the computer was relatively an unknown thing in India.

Currently he is  Professor Emeritus at Stanford.

He was Professor of Electrical Engineering at Stanford where he has pioneered the development of new wireless technology using multiple antennas. He invented the MIMO ( Multiple-Input & Multiple Output)   technology in 1992 enabling a way for the 5G technology we use today.

His research has also spanned emphasizing estimation theory, sensor signal processing, parallel computers architectures/algorithms, and space-time signal processing for wireless systems.

He seems to be a wizard in Wireless. Why we have to learn about such people from only Whats App posts pains me. His work is fit to be put into our school textbooks but unfortunately very few of us know about him.

 

Broadcom purchased Beceem Communications, a wireless semiconductor company founded by Paulraj in 2004 to help build its 4G and wireless business.

Intel acquired Iospan Wireless, a startup founded by Paulraj in 1998.

 

MIMO ( Multiple Input, Multiple Output) is a wireless technology that revolutionized broadband wireless internet for billions of people. MIMO improves both transmission data rates and expands network coverage. It is the essential foundation for all current and future broadband wireless communications.
