11. PERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKSPERFORMANCE ENHANCEMENT OF OFDM IN PAPR REDUCTION USING NEW COMPANDING TRANSFORM AND ADAPTIVE AC EXTENSION ALGORITHM FOR NEXT GENERATION NETWORKS
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : This paper presents a new hybrid PAPR reduction technique for the OFDM signal, which combines a multiple symbol representations method with a signal clipping method. The clipping method is a nonlinear PAPR reduction scheme, where the amplitude of the signal is limited to a given threshold. READ MORE

12. Designing of LTE-Advanced Downlink Transceiver on a Physical Layer
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : 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

13. Linearity Aspects of Dynamic PA Supply-Modulation Systems with Emphasis on Modulator Modeling and non-linearities
University essay from Avdelningen för elektronik, matematik och naturvetenskapAbstract : Modern communication systems operate with high peak-to-average-power ratio (PAPR) over wide bandwidth. Linearity requirements force operation in a low efficient highly linear back-off region. Then increasing efficiency is becoming critical. One of the most promising technologies to accomplish this is using supply modulation, e. READ MORE

14. Precoding in MIMO, OFDM to reduce PAPR (Peak to Average Power Ratio)
University essay from Institutionen för datavetenskap, fysik och matematik, DFMAbstract : 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

15. Performance Evaluation of LTE Physical Layer Using SC-FDMA & OFDMA
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : Since past few decades different types of cellular networks were launched and went successful on the radio links such as WiMAX, that became very popular because of its high data rate (70Mbps) and support for providing wireless internet services over 50km distance. The UMTS Long Term Evolution (LTE) is an emerging technology in the evolution of 3G cellular services. READ MORE
