Spectrum sensing over η-μ fading channel

Abstract

This paper presents the performance analysis of energy detection over generalized fading channels, modeled by the η-μ distribution. Receiver operation characteristics are obtained under several different fading scenarios, including low, typical, and severe fading conditions, with combining both multipath clusters and non-homogeneous environments. In addition, the improvement in detection capability is evaluated when cooperative spectrum schemes are employed under η-μ fading channel. Comparisons are performed against Rayleigh model and a great flexibility is found in spectrum sensing techniques when their formulations consider the use of the η-μ fading model.
