A novel signal independent technique for PAPR reduction in OFDM systems
New techniques for the reduction of peak to average power ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems are presented. These techniques are based on precoding the constellation symbols with Zadoff-Chu and Generalized Chirp-Like (GCL) precoders. The proposed techniques can...

| Summary: | New techniques for the reduction of peak to average power ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems are presented. These techniques are based on precoding the constellation symbols with Zadoff-Chu and Generalized Chirp-Like (GCL) precoders. The proposed techniques can achieve a PAPR reduction of up to 4.5 dB for OFDM systems. The techniques have been shown to be effective and have low complexity. © 2007 IEEE.
