Performance Evaluation for OFDM PAPR Reduction Methods
The ultimate goal of Peak to Average Power Ratio (PAPR) reduction for Orthogonal Frequency Division Multiplexing (OFDM) signals is to reduce the signal’s sensitivity to nonlinearity and to improve signal quality and transmitter power efficiency. Performance evaluation has traditionally been based mainly on the PAPR distribution curves. For clipping related methods, however, tradeoffs between PA...
متن کاملEvaluation and optimiztion of DRC-based PAPR-reduction within the DVB-T2 Common Simulation Platform
Orthogonal Frequency-Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation scheme, which is employed in the most advanced high-speed wireless communication systems, such as Digital Video Broadcasting (DVB) or Long-Term Evolution (LTE). However, one of its biggest shortcomings is that it produces a signal with a high Peak-to-Average Power Ratio (PAPR), which is undesirab...
متن کاملProposed Pilot Pattern Methods for Improvement DVB-T System Performance
Recently, orthogonal frequency division multiplexing (OFDM) has been extensively used in communications systems to resist channel impairments in frequency selective channels. OFDM is a multicarrier transmission technology in wireless environment that use a large number of orthogonal subcarriers to transmit information. OFDM is one of the most important blocks in digital video broadcast-terrestr...
متن کاملSynchronization Performance in DVB-T2 System
The Digital Video Broadcasting (DVB) project has developed digital broadcasting system specifications which have been adapted worldwide. The family of DVB standards includes DVB-S for satellite, DVB-C for cable and DVB-T for terrestrial system. This DVB-T system has proven its capability and thus accepted as the standard for terrestrial system in m o s t c o u n t r i e s. D V B-T 2 i s t h e e...
متن کاملImproved TKM-TR methods for PAPR reduction of DCO-OFDM visible light communications.
The dc-biased optical orthogonal frequency division multiplexing (DCO-OFDM) system is experimentally demonstrated as an appealing candidate in future visible light communication (VLC) system. However, the intrinsic high PAPR drawback that the DCO-OFDM system suffers from still needs to be addressed and few effective approach has been found so far. To deal with this problem, in this paper, the t...
