Yi Guo, Zheng Wang, Wenlin Zhang
RavenShield Weekly Meeting Jan. 24, 2011
Agenda
• Personnel changes• Feedback from the IPR meeting and discussion of
ideas• Plan for Spring 2011
Centralized vs. Distributed Spectrum Sensing
• Centralized Scheme:– Fusion center (common
receiver) – Reporting channels
• Distributed Scheme:– Local information
exchange without the central station

Secondary User (USRP)
About 10 - 20 USRPs are needed (currently 4 available).
Using Agilent signal generator to simulate different kinds of signal band, e.g., TV band, 3G, etc.
