Performance of Cooperative Spectrum Sensing in Log-normal Shadowing and Fading under Fusion Rules

Abstract

The performance of a cognitive radio (CR) user is sometimes limited due to severe fading or shadowing. In order to detect the primary user (PU) more accurately, we allow the CR users to cooperate by sharing their information. In this paper we investigate performance of single CR user and cooperative CR user based spectrum sensing (CSS) using energy detector… (More)
