Fractional low order cyclostationary-based spectrum sensing in cognitive radio networks
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we study the problem of cyclostationary spectrum sensing in cognitive radio networks based on cyclic properties of linear modulations. For this purpose, we use fractional order of observations in cyclic ...
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 ...
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 ...
