In One Week, Knightly Team Wins Two Best Paper Awards

June 25, 2015

This week the Rice Networks Group was awarded Best Paper at ACM MobiHoc 2015 and IEEE SECON 2015. Edward Knightly, Electrical and Computer Engineering Chair and Professor of ECE and Computer Science, helms the Rice Networks Group.

WATCH is the first system to enable secondary WiFi transmission even in the presence of kilowatt-scale TV transmitters, while simultaneously protecting TV receivers when they are active.

“We received FCC permission to test a system we designed in which we can take an active UHF TV channel, and despite the high transmission energy of TV, create a WiFi network using that channel,” explained Knightly.

The RNG group paper, “Scaling Multi-User MIMO WLANs: The Case for Concurrent Uplink Control Messages,” won best paper at IEEE SECON, held in Seattle. It was authored by recent ECE PhD graduate Oscar Bejarano, Rice wireless network engineer Sadia Quadri, professor Omer Gurewitz of Ben-Gurion University, and Knightly. 

This is the second year in a row the team has won best paper at SECON, with parallel research on making MU-MIMO more efficient. Previous research can be read here. Their 2015 paper can be read here
