   Abstract : To achieve cooperative diversity in cognitive radio network, Decode and Forward (DF) protocol is implemented at Cognitive Radios (CRs) using Orthogonal Space Time Block Coding (OSTBC). The 2-hop communication between source and destination is completed with the help of Cognitive Relays (CRs) using Multiple Input Multiple Output (MIMO) technology within the network. READ MORE

3. 2. DETECTION OF VACANT FREQUENCY BANDS IN COGNITIVE RADIO

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Ahmed Rehan; Ghous Yasir Arfat; [2010]
   Keywords : Cognitive radio; Spectrum Sensing ; Vacant Frequency bands; Spectrum Hole; Spectrum mobility; Cooperation strategies;

   Abstract : Cognitive radio is an exciting promising technology which not only has the potential of dealing with the inflexible prerequisites but also the scarcity of the radio spectrum usage. Such an innovative and transforming technology presents an exemplar change in the design of wireless communication systems, as it allows the efficient utilization of the radio spectrum by transforming the capability to dispersed terminals or radio cells of radio sensing, active spectrum sharing and self-adaptation procedure.
