Primary User Traffic Classification in Dynamic Spectrum Access Networks
Chun-Hao Liu, Przemysław Pawełczak, Danijela Cabric
This paper focuses on analytical studies of the primary user (PU) traffic classification problem. Observing that the gamma distribution can represent positively skewed data and exp…
Blind Estimation of Primary User Traffic Parameters Under Sensing Errors
Wesam Gabran, Przemysław Pawełczak, Chun-Hao Liu +1
In this work we investigate the bounds on the estimation accuracy of Primary User (PU) traffic parameters with exponentially distributed busy and idle times. We derive closed-form…
Multiple Antenna Cyclostationary Spectrum Sensing Based on the Cyclic Correlation Significance Test
Paulo Urriza, Eric Rebeiz, Danijela Cabric
In this paper, we propose and analyze a spectrum sensing method based on cyclostationarity specifically targeted for receivers with multiple antennas. This detection method is used…
Eigenvalue-based Cyclostationary Spectrum Sensing Using Multiple Antennas
Paulo Urriza, Eric Rebeiz, Danijela Cabric
In this paper, we propose a signal-selective spectrum sensing method for cognitive radio networks and specifically targeted for receivers with multiple-antenna capability. This met…
Cramer-Rao Bounds for Joint RSS/DoA-Based Primary-User Localization in Cognitive Radio Networks
Jun Wang, Jianshu Chen, Danijela Cabric
Knowledge about the location of licensed primary-users (PU) could enable several key features in cognitive radio (CR) networks including improved spatio-temporal sensing, intellige…
Weighted Centroid Algorithm for Estimating Primary User Location: Theoretical Analysis and Distributed Implementation
Jun Wang, Paulo Urriza, Yuxing Han +1
Information about primary transmitter location is crucial in enabling several key capabilities in cognitive radio networks, including improved spatio-temporal sensing, intelligent…
