Distributed detection(DD) is an area of interest in the Cognitive Radio(CR) Network domain. With the help of geographically dispersed sensors and a Fusion Center(FC) (i.e. the network element which generates the global network decision), a DD system can determine the presence or absence of a primary user signal. This prevents any harmful interference by a secondary user who is trying to gain access to the unoccupied spectrum opportunistically. DD system gained its popularity in spectrum analysis due to the limited bandwidth of the reporting channels between the sensors and their fusion center.
