Full-duplex Wireless Communications: In 2010, we re-purposed off-the-shelf MIMO radios used in WARP platform to develop a single-channel full-duplex wireless communication system. Combining a mix of experiment-driven data modeling and information-theoretic analysis, we have shown that full-duplex is a definite reality for short to medium range communications. Full-duplex is adopted in cable modems and demonstrated in 5G. Awarded 2017 IEEE Jack Neubauer Memorial Award and 2018 The IEEE Communications Society Award for Advances in Communications (equivalent of the ACM Test-of-time award for Communications Theory). See more details here.
“Distributed” Network Information Theory: Local View Capacity: Mismatched and incomplete network state information, aka local view, is a reality in all wireless networks. Yet, there have been no effort to develop information theoretic capacity of networks with a local view. Started in 2009, see some of the key publications. Read a short overview of the main concepts here.
Wireless Open-Access Platform (WARP): Started in 2006,Wireless open-Access Research Platform WARP, was adopted by 150+ organizations worldwide, has been used in over 500+ research papers (see many listed here) and forms the core for Rice Argos project. Rice Argos project also led to a spin-off Skylark Wireless, which became the basis for Rice RENEW project. WARP was awarded 2019 ACM Sigmobile Test-of-time Award.
