Performance Analysis of Cooperative Spectrum Sensing in Suzuki Fading Channels

Abstract

This paper examines the performance of cooperative spectrum sensing, using energy detection, in Suzuki fading channels. Sub-optimal centralized detection approaches are examined where decisions are made based on identical tests performed at the individual radios. Decisions are performed at a fusion center using a counting rule that encompasses the OR, AND, and majority rules as special cases. Analytical and simulation results are presented for Rayleigh, Log-normal and Suzuki distributions.
