Former CTO, Mobile & Wireless, Broadcom Corporation, Ph.D. - Rensselaer Polytechnic Institute
Nambi Seshadri is currently Professor of Electrical and Computer Engineering at University of California, San Diego (UCSD). He also serves as a senior technical advisor to Quantenna Communications and a few start ups.
Prior to joining UCSD, he was with Broadcom corporation which he joined in 1999. He was the first employee dedicated to developing the company’s wireless strategy which initially began with wireless connectivity products and subsequently entered the cellular baseband market. As CTO of the Mobile Platforms and Wireless Connectivity business groups, he helped drive Broadcom’s entry into 2G and 3G cellular, mobile multimedia, low power Wi-Fi for handsets, combo chips that integrate multiple wireless connectivity technologies, GPS, 4G technologies, as well as development of a strong IPR portfolio.
Prior to joining Broadcom, he served more than 13 years with AT&T, first as a member of the technical staff in the Signal Processing Research Department of AT&T Bell Laboratories and later as Head of Communications Research at AT&T Shannon Labs. His research has been focused on developing techniques for reliable transmission of data, speech, and audio for mobile communications.
During the first few years at Bell Labs, his research collaborations resulted in novel techniques for understanding the impact of channel errors on low bit rate speech coders resulting in combined speech and channel coding and decoding solutions. In the 1990s, he co-invented space-time trellis codes with Vahid Tarokh and Robert Calderbank and their paper on this topic won the 1999 IEEE Information Theory Society Best Paper Award.
Another paper on the implementation of a modem based on space-time coding (co-authored with Tarokh, Calderbank and Ayman Naguib) was selected by IEEE Communications Society in 2002 as one of the 50 most influential works published by IEEE Communications Society in its first 50 years - The Best of Best: 50 Years of Communications and Networking Research.
These and additional works on space-time codes from AT&T and other institutions resulted in the rapid establishment of space-time codes as an important area of wireless communications.
He also helped drive adoption of hybrid ARQ in EDGE cellular transmission as a technique for robust link adaptation.
Nambi received a B.E. degree in Electronics and Communications from Regional Engineering College (now called NITT), Tiruchirapalli, India, and a M.S. and Ph.D. from Rensselaer Polytechnic Institute, Troy, NY. He is a Member of National Academy of Engineering, a Fellow of IEEE, Distinguished alumnus of National Institute of Technology, Tiruchirapalli, India and holds more than 75 patents.
