4. 3. 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
