1. 21. 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

4. 23. Precoding in MIMO, OFDM to reduce PAPR (Peak to Average Power Ratio)

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Muhammad Irfan Ishaq; Yasir Ali Khan; Muhammad Talha Gul; [2012]
   Keywords : Peak to Average Power Ratio;

   Abstract : One of the critical issues of systems utilizing Orthogonal Frequency Division Multiplexing (OFDM) is the high peak to the average power ratio of OFDM signals. We have used Precoding as a way to mitigate the PAPR problem. Furthermore the performance of Precoded OFDM in fading multi-path channels has been studied. READ MORE
