ITA / ECE 293 Seminar: Massive MIMO Full-duplex: Theory and Experiments

11:00 AM - 12:00 NOON
Atkinson Hall, Room 4004

Professor Young-Han Kim
Ashutosh Sabharwal, Department of Electrical and Computer Engineering, and Scalable Health Initiative, Rice University

Full-duplex wireless, which allows nodes to send and receive simultaneously in the same frequency band, has gain recent attention due to experimental demonstrations. In this talk, we will discuss an all-digital architecture for implementing full-duplex in systems with many antennas (10s to 100s). The new architecture, SoftNull, allows us to use current half-duplex radios on base-stations to implement full-duplex capability. We will present an signal dimension analysis of potential spectral efficiency gains, and then present experimental results from Rice large array called Argos (

Speaker Bio: 

Ashutosh Sabharwal is a Professor of Electrical and Computer Engineering in Rice University, Houston, Texas. He is the founder of WARP project (, an open-source project which is now in use at more than 125 research groups worldwide, and have been used by more than 250 research articles. His research has spanned both fundamental theory and experimental systems. He is a Fellow of IEEE for his contributions to the theory and experimentation in wireless systems and communications. These days, he is also working on a second research area and has founded the Rice Scalable Health Initiative ( The goal of the new initiative is both foundational research, and technology translation to make measurable impact in healthcare and wellness. His past research has led to two commercial spinoffs, Mango Communications to commercialize WARP (, founded in 2008) and Cognita Labs to develop novel chronic care products (, founded in 2013).
