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…
Throughput and Collision Analysis of Multi-Channel Multi-Stage Spectrum Sensing Algorithms
Wesam Gabran, Przemysław Pawełczak, Danijela Čabrić
Multi-stage sensing is a novel concept that refers to a general class of spectrum sensing algorithms that divide the sensing process into a number of sequential stages. The number…
