Arogyaswami J. Paulraj is an Emeritus Professor at Stanford University. After a 25 years of R&D service in the India, Paulraj joined Stanford University in 1991. He proposed the MIMO (Multiple Input Multiple Output) concept in 1992 which is the key to today’s 4G cellular and WiFi wireless networks.
Paulraj is an ISI Thomson most highly cited researcher with two textbooks on MIMO. He has published over 350 archival papers and a co-inventor in over 63 patents. He has graduated over 50 doctoral and post-doctoral students at Stanford.
Paulraj has over 30 recognitions which include the two top global awards in telecommunications - the 2014 Marconi Prize and the 2011 IEEE Alexander Graham Bell medal. He is a member of eight National Academies in Engineering / Sciences including those of United States of America, India, PR China, Sweden and The World Academy of Sciences. He is a fellow of IEEE and AAAS. He has received a number of recognitions in India including the Padma Bhushan, the nation’s third highest civilian honor.
In 1999, Paulraj founded Iospan Wireless Inc. and the company was acquired by Intel Corp in 2003. Iospan pioneered MIMO-OFDMA used in 4G technology. In 2003, Paulraj co-founded Beceem Communications Inc. which became the leader in 4G / WIMAX chip sets. Beceem was acquired by Broadcom Corp. in 2010. In 2014 he founded Rasa Networks for WiFi Network Analytics. Rasa was acquired by HPE in 2016. In India he also co-founded Spectrum Infotech Ltd., in 1993, an electronics design company, acquired by L&T Ltd. in 2008.
Paulraj’s main lifetime contributions were in India between 1965 to 1990. His work there spans sonars and high-speed computers. From 1972 to 1983 he led the development of sonars for the Indian Navy. Most notable is the APSOH sonar that entered fleet service in 1983 and is recognized as a landmark military electronics achievement in India. Between 1988–91, Paulraj also co-led the development of a parallel computer (PARAM). Paulraj’s other contributions in India also included the founding of three Government R&D laboratories - Center for Artificial Intelligence and Robotics, Central Research Labs (Bharat Electronics) and the Center for Development of Advanced Computing.
Paulraj’s current research interests are in 5G cellular and millimetric band technology for broadband terrestrial, HAP and satellite networks. He serves on a number of company boards in the US and India.
Paulraj is a Visiting Professor at the Imperial College, London, a Distinguished Professor at the Indian Institute of Technology Madras, India and a IGAT Visitor at the Beijing Institute of Posts and Telecommunications, Beijing, China.
