2. Performance Analysis of 3-hop using DAF and DF over 2-hop Relaying Protocols
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : In wireless Communication, the need of radio spectrum increases nowadays. But in the system we are losing approximately 82-86% of spectrum most of the time due to the absence of Primary User (PU). To overcome this issue Cognitive Radio (CR) is an admirable approach.

3. 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

4. Directional Spectrum Sensing and Transmission Using a Sector Antenna
University essay from Institutionen för informationsteknologi och medierAbstract : Spectrum sensing plays a key role for radio resource awareness in cognitive radio. To enhance the capabilities of cognitive radio nodes, exploiting the spatial resource in addition to frequency and time re-sources seems reasonable. READ MORE

5. Spectrum Sensing in Cognitive Radio Systems using Energy Detection :
University essay from Avdelningen för elektronik, matematik och naturvetenskapAbstract : Cognitive radio is a low-cost communication system, which can choose the available frequencies and waveforms automatically on the premise of avoiding interfering the licensed users. The spectrum sensing is the key enabling technology in cognitive radio networks. READ MORE
