Arogyaswami J. Paulraj AVSM, VSM (born 14 April 1944) is a distinguished Indian-American electrical engineer. A former Commodore in the Indian Navy, he is currently a Professor Emeritus in the Dept. of Elect. Engineering at Stanford University.
Paulraj was born in Pollachi near Coimbatore, India, one of six children of Sinappan Arogyaswami and his wife Rose. He joined the Indian Navy at age 15 through the National Defence Academy, Khadakvasla and served the Navy for 30 years. Paulraj received his bachelor's degree in electrical engineering from the Naval College of Engineering, Lonavala, India, and his doctorate in electrical engineering from the Indian Institute of Technology, New Delhi.
Paulraj is the pioneer of a breakthrough wireless technology known as MIMO (multiple input, multiple output) that dramatically increases performance of wireless systems. MIMO is now core technology in latest WiFi and LTE systems. Paulraj served in India till 1991 where he is known for pioneering the development of military sonars (APSOH family). Paulraj also served as the founding director for three major labs in India - Centre for Artificial Intelligence and Robotics (CAIR), CDAC (Center for Development of Advanced Computing) and CRL (Central Research Labs of Bharat Electronics).
Paulraj’s MIMO technology is now crucial to local area and mobile wireless communications. MIMO allows both higher data rates and wider coverage areas. MIMO technology involves using multiple antennas at both the transmit station and the receive station. Efficiency is increased because parallel streams of data can be multiplexed within the same channel.
