ABSTRACT

This chapter investigates the performance of energy-detection-based spectrum sensing over η-λ-µ fading distribution. Novel analytic expressions are derived for the average probability of detection. These results for single user detection are then extended to square low selection (SLS) diversity and for collaborative detection cases. Since η-λ-µ includes the Nakagami-m, the Rayleigh, the one-sided Gaussian, Hoyt, the λ-µ and the η-µ distributions as special cases, the analysis for η-λ-µ distribution provides analysis for all these fading channels. The analysis for fading is then extended to composite fading and shadowing. Receiver operating characteristic (ROC) curves are presented for different scenarios using the derived expressions. The effect of different parameters on the average probability of detection is analyzed.
