초록

In this paper, we proposed new scheme to reduce the Peak-to-Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) system OFDM system is highlighted for multi-media communication system, however it has large PAPR. To reduce the PAPR in OFDM system, several techniques have been proposed such as clipping, coding and so on Our proposed method is a case of block coding and proposed system be termed Sub-Coding OFDM (SC-OFDM) system We also compare the performance between conventional and our proposed OFDM system by computer simulation.
