Spectrum-Aware Orthogonal Frequency Division Multiplexing
(Virginia Tech, 2010-12-15)
Reconfigurable computing architectures are well suited for the dynamic data flow processing requirements of software-defined radio. The software radio concept has quickly evolved to include spectrum sensing, awareness, and ...
Cognitive Radio Engine Design for Link Adaptation
(Virginia Tech, 2010-09-07)
In this work, we make contributions in three main areas of Cognitive Engine (CE) design for link adaptation. The three areas are CE design, CE training, and the impact of imperfect observations in the operation of the ...
A Model based Design Framework for Interoperable Communication Systems
(Virginia Tech, 2010-08-12)
The need for interoperability in emergency communication systems has hastened the development of cognitive radio technology. However, even though a cognitive radio system technically interconnects participating agencies, ...
