This article addresses the impact of forward error correction when applied to the report channel transmissions of a centralized decision fusion cooperative spectrum sensing scheme designed to detect idle ...
In the situations in which error correction is effective, the Repetition code is capable of outperforming the BCH, meaning that the diversity gain may be more relevant than the coding gain when the spectrum ...
Moreover, the current fixed spectrum allocation policy, which only benefits licensed users, also called primary users (PUs), has been the major reason for the underutilized spectral resources, since studies ...
