— Next generation wireless networks will be heterogeneous, where several primary users (PU e.g. licensed users) and secondary users (SU e.g. unlicensed users) can operate in the ...
Abstract—Cognitive radio is a key enabling technology of dynamic spectrum access for exploiting unused spectrum resources. This article focuses on modeling the opportunity for ce...
— This paper presents an architecture for adaptive cognitive radio networks based on the concept of a “global control plane”. The proposed control architecture uses a predete...
— With the advent of cognitive radio technology, new paradigms for spectrum access can achieve near-optimal spectrum utilization by letting users sense and utilize available spec...
This paper presents the application of cognitive algorithm for a stream diffusion in home theatre “5+1 audio” surround applications. We develop a wavelet-based method to effic...
