Cognitive radio is widely expected to be the next Big Bang in wireless communications.
Spectrum sensing, that is, detecting the presence of the primary users in a licensed …

Spectrum sensing is the key to coordinate the secondary users in a cognitive radio network
by limiting the probability of interference with the primary users. Linear cooperative spectrum …

In this paper, we present a probabilistic inference approach for cooperative spectrum
sensing. We probabilistically model the cooperative sensing system on a representative …

This paper investigates the problem of cooperative spectrum sensing in cognitive radios with
unknown parameters in the likelihood function. We first derive the optimal likelihood ratio …

Spectrum sensing is an important function for dynamic spectrum access (DSA) type
cognitive radio systems to detect opportunities for sharing the spectrum with a primary …

In the dynamic spectrum access (DSA) type of cognitive radios, secondary users need to
detect the signals from the primary system prior to communicating in the sharing band …

In this paper, we consider a wideband cognitive radio system that operates over multiple idle
subchannels. A joint optimization of sensing threshold and transmission power is proposed …

This paper considers coded multichannel cooperative spectrum sensing (MC-CSS)
employing local Neyman-Pearson testing at each sensor and channel decoding integrated …

This paper considers the integration of channel decoding with fusion based decision, for
coded collaborative spectrum sensing (CSS) employing local Neyman-Pearson (NP) testing …

Spectrum sensing is a critical step in cognitive radio based DSM to learn the radio
environment. Despite its long history, in the past decade, the study on spectrum sensing has …
