The Past Shapes the Present

Born in India, Paulraj joined the Indian Navy at age 15. The Navy sent him to the Indian Institute
of Technology (Delhi), where he earned a Ph.D. for advances to signal filtering theory. The loss
of an Indian naval ship from submarine action in the 1971 Indo-Pakistan War brought Paulraj to
sonar technology and he advanced the Indian Navy’s sonar capability.
In 1977, he led the design of the APSOH sonar which became the fleet sonar of the Indian Navy, ushering in India’s global leadership in this vital technology. Paulraj later founded three national labs in India spanning
artificial intelligence, computing and military electronics, before joining the faculty at Stanford
University. Shortly after joining Stanford, he identified surprising results in signal separability
that became the genesis of MIMO.
A Powerful Innovator
Dr. Paulraj pioneered Multiple Input, Multiple Output (MIMO), a wireless technology that has revolutionized broadband wireless internet access for billions of people worldwide. MIMO improves both transmission data rates and expands network coverage. It is the essential foundation for all current (Wi-Fi and 4G mobile) and future broadband wireless communications.
Leaving A Lasting Impression in Telecom
Paulraj founded Iospan Wireless Inc. (acquired by Intel), and developed a MIMO-based cellular wireless technology that became the basis for WiMAX and LTE mobile networks. He also cofounded Beceem Communications (acquired by Broadcom), which became a global leader in WiMAX semiconductors. Currently professor emeritus at Stanford, Paulraj holds 79 patents and has received numerous awards, including the 2014 Marconi Prize.
