2. Performance Analysis of a MIMO Cognitive Cooperative Radio Network with Multiple AF Relays
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : With the rapid growth of wireless communications, the demand for the various multimedia services is increasing day by day leading to a deficit in the frequency spectrum resources. To overcome this problem, the concept of cognitive radio technology has been proposed which allows the unlicensed secondary user (SU) to access the licensed spectrum of the primary user (PU), thus improving the spectrum utilization.

3. Exploiting the Direct Communication Link for Enhancing Effective Capacity Performance of Cognitive Radio Relay Networks
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : Nowadays, cognitive radio (CR) is a promising concept to improve the radio spectrum exploitation. CR has tremendous ability to enhance spectrum efficiency by allowing secondary users (SUs) to access licensed radio spectrum resource which is currently not being used by primary users (PUs).

5. Impact of Interference from Primary User on the Performance of Cognitive Radio Networks
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : This thesis report presents background knowledge about cognitive radio network (CRN) and investigates performance of underlay cognitive radio networks based on an adaptive power allocation policy of secondary transmitter (SU-Tx). In particular, it has been assumed that SU-Tx and primary user transmitter (PU-Tx) are equipped with a single antenna, while the corresponding receivers are equipped with multiple antennas. READ MORE
