1. 31. Adaptive Modulation for Dual-Hop Amplify-and-Forward Relaying Networks with Partial Relay Selection under Co-Channel Interference

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Sohaib Ahmed Siddiqui; Mohammad Abbas Khan; [2013]
   Keywords : Amplify-and-forward; BER; Outage Probability; SNR; Spectral Efficiency;

   Abstract : A new era of wireless communications combats with many challenges, including the performance issues and the demand of higher data rate. Upcoming generations of wireless communications will bear the resemblance in terms of same issues. READ MORE

3. 32. Performance Evaluation of 2-Hop and 3-Hop Relay Network using DF, AF and DAF Relaying Protocols

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Mohsin Kamal; Theera Yukong; [2012]
   Keywords : Amplify and Forward; Decode and Forward; Decode Amplify and Forward; Relay network; 2-hop and 3-hop cognitive radio networks ;

   Abstract : Cognitive radio is an evolving wireless technology employed to increase the frequency spectrum utilization of the limited spectral resources. Cooperative communications has been established as a potential method of solving the fading effects in wireless communications, improving the reliability of network performance, network throughput, and adaptability.

4. 33. 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).

5. 34. Antenna diversity with opportunistic combining

   University essay from Fysik och elektroteknik; Tekniska högskolan

   Author : Md. Khalilur Rahman; Chuanhui Xia; [2012]
   Keywords : ;

   Abstract : In modern telecommunication technologies, the requirement for signal reliability is higher and higher but fading is the main challenge for signal reliability. Different types of techniques have been studied to mitigate this fading but MIMO (Multiple Input Multiple Output) has been studied extensively in wireless communication systems to overcome small-scale fading, which is an efficient way to improve signal-to-noise and bit error rates.
