5. 19. 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).
