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.
Their paper, “WATCH: WiFi in Active TV Channels,” authored
by ECE graduate student Xu Zhang and Knightly, won best paper at ACM MobiHoc
2015, held in Hangzhou, China.
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.

Knightly’s previous UHF work here.
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
