3. 22. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Samiallah Shahid; Saqib Mohammad; [2013]
   Keywords : LTE-Advanced; Downlink; Transceiver; Physical Layer;

   Abstract : The evolved version of LTE is LTE-Advanced which is being developed by 3GPP. LTE-Advanced will meet or go beyond the requirements of the International Telecommunication Union (ITU) for the fourth generation (4G) radio communication standard known as IMT-Advanced. LTEAdvanced is primarily considered as a part of Release 10 of 3GPP specifications. READ MORE

5. 24. Capacity Analysis of Cognitive Radio Relay Networks under Transmission and Interference Power Constraints

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Abhijith Gopalakrishna; [2012]
   Keywords : effective capacity; outage capacity; ergodic capacity; cognitive radio; relay networks;

   Abstract : This thesis investigates the performance of cognitive radio relay networks (CRRN) in Rayleigh fading channel under various power constraints. Here spectrum sharing approach is considered, whereby a secondary user (SU) may be allowed to transmit simultaneously with a primary user (PU) as long as SU interference to PU remains below a tolerable level.
