Performance Analysis of Primary User Detection in a Multiple Antenna Cognitive Radio
— We consider the problem of detecting a primary user signal over a wireless channel by a cognitive radio with multiple antennas. We present a multiple antenna processing based e...

Multiple antenna spectrum sensing in cognitive radios
In this paper, we consider the problem of spectrum sensing by using multiple antenna in cognitive radios when the noise and the primary user signal are assumed as independent compl...

Multiantenna detection under noise uncertainty and primary user's spatial structure
Spectrum sensing is a challenging key component of the Cognitive Radio paradigm, since primary signals must be detected in the face of noise uncertainty and at signal-to-noise rat...

Primary User Enters the Game: Performance of Dynamic Spectrum Leasing in Cognitive Radio Networks
Dynamic spectrum leasing (DSL) is one of the schemes proposed for dynamic spectrum sharing (DSS) in cognitive radio networks. In DSL, spectrum owners, denoted as primary users, dyn...
