Reducing the peak to average power ratio in OFDM systems
High peak to average power ratio of the transmit signal is a major drawback of OFDM systems. After defining the PAPR and analyzing its statistical properties, some of the most representative PAPRreduction techniques available in the literature are reviewed in detail. Several methods have been proposed to reduce the peak power of OFDM signals. In this paper the effectiveness of some recently pro...
متن کاملCompanding Technique for Reducing Peak-to-Average Power Ratio in OFDM Linear Coded Systems
Orthogonal Frequency division multiplexing (OFDM) is a very attractive technique in wireless communications which provides robustness to channel fading and immunity to impulse interference. Despite of its advantages, one of the major drawbacks of OFDM system is very high peak-to-average power ratio (PAPR). Among the various PAPR reduction techniques, companding appears attractive for its simpli...
متن کاملNear Shannon Limit and Reduced Peak to Average Power Ratio Channel Coded OFDM
Solutions to the problem of large peak to average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems are proposed. Although the design of PAPR reduction codewords has been extensively studied and the existence of asymptotically good codes with low PAPR has been proved, still no reduced PAPR capacity achieving code has been constructed. This is the topic of the curre...

متن کاملPcc-ofdm with Reduced Peak-to-average Power Ratio
Polynomial cancellation coded orthogonal frequency division multiplexing (PCC-OFDM) with overlapping symbol periods is a modulation technique which overcomes many of the disadvantages of OFDM. PCCOFDM is much less sensitive to frequency offset and Doppler spread than OFDM. PCC-OFDM like OFDM has a high peak-to-average power ratio (PAPR). In this paper it is shown that the PAPR can be reduced wi...
