Non-uniform quantized distributed sensing in practical wireless rayleigh fading channel
( Springer Verlag , 2015 , Conference Paper)In this paper, we study non-uniform multilevel quantization problem in cognitive radio networks (CRNs). We consider a practical collaborative spectrum sensing (CSS) scenario in which secondary users (SUs) cooperate with ... -
Optimization of collaborative spectrum sensing with limited time resource
( Springer Verlag , 2015 , Conference Paper)In this paper, Cognitive Radios (CRs) collaborate in spectrum sensing to detect random signals corrupted by Gaussian noise. Our analysis is based on a limited time resource assumption. This implies that the time resource ... -
Optimization of probability of error in collaborative spectrum sensing of time-limited cognitive radio networks
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time resources in cognitive radio (CR) networks. The frame structures for sensing and data transmission, if the ... -
Secure robust collaborative spectrum sensing in the presence of smart attackers
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, collaborative spectrum sensing to detect random signals corrupted by Gaussian noise in the presence of smart attackers is studied. Unlike to the most of related works, we consider a blind attacker detection ...
