1. Robust MIMO Precoding on Real-World Measured Channels
Master-uppsats, KTH/SignalbehandlingSammanfattning : It is well known that multi-input multi-output (MIMO) wireless communication systemsthat employ precoding techniques are capable of meeting the high expectations of modernand future wireless communication standards. In order to fully utilize these techniques, thecommunication system typically requires information of the channel, commonly referred toas channel state information (CSI). LÄS MER
2. Performance Analysis of 3-hop using DAF and DF over 2-hop Relaying Protocols
Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapSammanfattning : 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. Performance Analysis of OSTBC with Hybrid Decode-Amplify and Forward relay network
Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapSammanfattning : In the last few decades, the innovation of Wireless communication has been developed very fast in order to improve the performance of communication systems. Especially,a concept of Multiple Input and Multiple Output (MIMO) is purposed to fulfill a high data rate service such as high quality video conference. LÄS MER
4. Performance Analysis of Decode and Forward Relaying with Keyhole in Nakagami-m Fading Channels
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknikSammanfattning : Fading has always been a major obstacle in the effective transmission of signals from the transmit antenna to the receive antenna. The innovation of multiple-input multiple-output (MIMO) system has led to the regression of the adverse effect of these fading entities and thus provided a higher data rate communication while maintaining the quality of service (QoS).
