Arogyaswami Paulraj

Paulraj was born in Pollachi near Coimbatore, British India in 1944, one of six children of Sinappan Arogyaswami and his wife Rose.[2] He joined the Indian Navy at age 15 through the National Defense Academy, Khadakvasla and served the Indian Navy for 26 years. Paulraj received a B.E. in electrical engineering from the Naval College of Engineering, Lonavala, India, and a Ph.D. in electrical engineering from the Indian Institute of Technology, New Delhi, India[3]

Paulraj's contributions in India came whilst serving in the Indian Navy. In 1972, he developed new electronics for a British origin Sonar 170B. The technology was widely deployed in the Indian fleet. During 1977- 83, Paulraj led the development of a large surface ship sonar APSOH. This became the fleet sonar for the Indian Navy and its variants are still widely deployed. APSOH was a landmark achievement in Indian Electronics. Later, Paulraj founded three national-level research centers in India: the Center for Artificial Intelligence and Robotics, Defense R&D Organization, the Central Research Laboratories, Bharat Electronics, and the Center for Development of Advanced Computing, Dept. of Electronics (as co-founder). These labs are now a part of India's vast R&D infrastructure. He retired prematurely from the Indian Navy in 1991 with a rank of Commodore [4]

Moving from India, Paulraj joined Stanford University faculty in 1992. His invention (1992) for exploiting multiple antennas at both ends of a wireless link (MIMO) lies at the heart of the current high speed WiFi and [[4G] /[5G] ] mobile networks, and has revolutionized high-speed wireless services for billions of people. MIMO boosts data rate by creating parallel data streams, multiplying throughput by the number of antennas used. He ran a MIMO research program at Stanford for two decades before retiring in 2010. He founded three companies: Iospan Wireless for MIMO-OFDMA core technology (acquired by Intel),[5] and Beceem Communications for 4G chips (acquired by Broadcom),[6] have helped create a wireless technology eco-system now shipping billions of MIMO wireless devices annually. He founded Rasa Networks (acquired by Aruba /HPE) for using AI tools in WiFi network analytics.[7]

Paulraj has two textbooks on MIMO.,[8] over 400 archival research publications and a co-inventor in 80 patents.[9]
