Google Scholar Profile


Dr. Naga Bhushan graduated from IIT Madras in 1989 with a Bachelors’ degree in Electrical Engineering. He obtained a Masters’ and Ph.D. in Electrical Engineering from Cornell University in Ithaca, New York. With more than two decades of contributions in the telecommunications sector, he is responsible for advancement of communication theory and for innovative implementation leading to the commercial realization of Broadband Wireless Technologies such as 3G (EV-DO), 4G (UMB, LTE, LTE-A, LTE-U) and 5G-NR. In his role as the Vice President, Technology at Qualcomm Inc. he has been at the helm of technologies that are the bedrock of the current smartphone revolution. Dr. Naga Bhushan has made significant and innovative technical contributions to the design and development of EV-DO, the first high-rate, wide-area wireless packet data system to be widely commercialized. His main areas of contribution include waveform design, channel coding and modulation schemes, antenna diversity schemes, link adaptation techniques, handoff algorithms, power control, QoS-aware scheduling algorithm and the functional architecture of the forward link demodulator. He has led the design and standardization of the OFDM-based broadcast/multicast service for EV-DO, and of an OFDMA-based wide-band wireless packet data system (UMB) in the 3GPP2 standards forum. He has actively contributed to R&D efforts involving Interference Management/Cancellation, Heterogeneous Networks, Multi-hop/relays, Ultra-dense networks for LTE-Advanced, LTE for unlicensed spectrum (LAA/eLAA) and direct (peer-to-peer) communication, and New Radio for 5G wireless systems (design principles for a universal air-interface, including mm-Wave band and UR-LLC operation). He has developed key insights and identified the main design elements that formed the basis of the systems mentioned above. Dr. Naga Bhushan has published his research and findings in 26 international journals and conferences, and has nearly 400 issued US patents spanning 3G, 4G and 5G wireless systems (3000+ worldwide), with over 150 active patent applications. As part of his service to the community, he is serving as an Adjunct Faculty for Amrita Center for Wireless Networks and Applications, Amrita Vishwa Vidyapeetham, Amritapuri, offering a Masters’ level course titled ‘MIMO Communication Systems’.
