Peak-to-Average Power Ratio Reduction in OFDM system using Block Coding technique
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2012, Vol 1, Issue 7
Abstract
One of the challenging issues for Orthogonal Frequency Division Multiplexing (OFDM) system is its high Peak-to-Average Power Ratio (PAPR). In this paper, we 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. The results show that, at the same coding rate 3/4, the proposed scheme can achieve almost the same performance as the cyclic code but with lower complexity. But under the same coding rate, the PAPR reduction obtained by using SBCC is better than the rest schemes. The flexibility on choosing the coding rate and low complexity makes that the proposed scheme SBCC is more suitable for the large frame size with high coding rate and can provide error detection..We also discuss some methods of PAPR Reduction.
