1. 1. Robust MIMO Precoding on Real-World Measured Channels

   University essay from KTH/Signalbehandling

   Author : Filip Hedenskog; [2015]
   Keywords : MIMO; maximin; imperfect CSIT; real-world measured channels; uncertainty set; worst-case robustness;

   Abstract : 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). READ MORE

3. 2. Performance Analysis of 3-hop using DAF and DF over 2-hop Relaying Protocols

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Faisal Mehmood; Muneeb Ejaz; [2013]
   Keywords : Bit Error Rate; Cognitive Radio; Decode Amplify and Forward; Energy Detection; Probability of Detection; Rayleigh Fading; Relay Network;

   Abstract : 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. READ MORE

4. 3. Performance Analysis of OSTBC with Hybrid Decode-Amplify and Forward relay network

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Kanoksak Wannatrong; Mohammed Abul Hayat; [2013]
   Keywords : Cooperative communication; symbol error rate; moment generating function; orthogonal space-time block code. ;

   Abstract : 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. READ MORE

5. 4. Performance Analysis of Decode and Forward Relaying with Keyhole in Nakagami-m Fading Channels

   University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

   Author : pawan khadka; [2012]
   Keywords : decode and forward; orthogonal space time block codes; Nakagami-m fading; keyhole effects; symbol error rate; moment generating function; fading severity parameter;

   Abstract : 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).
