Detection of temporally correlated primary user signal with multiple antennas
( Springer Verlag , 2015 , Conference Paper)In this paper, we address the problem of multiple antenna spectrum sensing in cognitive radios (CRs) when the samples of the primary user (PU) signal as well as samples of noise are assumed to be temporally correlated. We ... -
On the Higher Order Statistics of the Channel Capacity in Dispersed Spectrum Cognitive Radio Systems Over Generalized Fading Channels
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)This work is devoted to the study of dispersed spectrum cognitive radio (CR) systems over independent and nonidentically distributed (i.n.i.d.) generalized fading channels. More specifically, this is performed in terms of ... -
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 ... -
Performance analysis of relay selection schemes in OFDM-based underlay cognitive networks
( IEEE , 2013 , Conference Paper)Cognitive radio (CR) is a promising technology that allows wireless systems to sense the environment and learn from previous experience to improve the communication quality. However, CR needs a flexible and adaptive physical ... -
Performance of eigenvalue based spectrum sensing in full-duplex cognitive radio networks
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)Spectrum sensing is a key component in any cognitive radio network. Recently full-duplex communication, i.e., the ability to transmit and receive at the same time at the same frequency, has become feasible. Residual self ...
