Peak-to-Average Power Ratio Reduction in OFDM System Using Block Coding Technique

One of the challenging issues for Orthogonal Frequency Division Multiplexing (OFDM) system is its high Peak-to-Average Power Ratio (PAPR). In this paper, the authors review and analysis different OFDM PAPR reduction techniques, based on computational complexity, bandwidth expansion, spectral spillage and performance the proposed scheme is termed Sub-Block Complement Coding (SBCC). Performance results obtained with SBCC are given and compared with that of the standard Complement Block Coding (CBC), Cyclic Coding (CC), Simple Block Coding (SBC), Modified Simple Block Coding (MSBC) and Simple Odd Parity Code (SOPC) for the same purpose.
