Paulraj began his professional career in India before moving to academic and research roles in the United States. His early career was associated with the Indian Navy, where he worked on signal processing and sonar-related technologies. He subsequently joined Stanford University, where his research focused on array signal processing and wireless communications.
Paulraj is recognised for proposing the use of multiple antennas at both the transmitter and receiver to improve wireless link capacity, a concept central to MIMO. MIMO techniques have since become a foundational element of high-speed wireless standards, including modern Wi-Fi and cellular systems such as LTE and successor generations. His research has influenced both academic study and industrial deployment of advanced antenna systems.
In addition to his academic work, Paulraj has been involved in technology entrepreneurship, founding and advising companies focused on wireless communications and signal processing. This combination of academic research and industry engagement has placed him among notable figures bridging engineering research and commercial wireless technology.
Paulraj has received numerous honours from professional engineering societies for his contributions to communications technology. He is regarded as a leading figure in the wireless engineering community.
