  Abstract

DFT (discrete Fourier transform) spread OFDM is used a lot to solve high PAPR problem of OFDM (orthogonal frequency division multiplexing) system. However, PAPR is increased again in DFT spreading OFDM system when comb type pilot is inserted because comb type allocation of pilot is needed to estimate channel characteristics. So, in this paper, we apply a SLM (selective mapping) method to DFT spreading OFDM system to reduce increased high PAPR characteristics. And we suggest an effective method to transmit side information without additional bandwidth. Also, we propose an adaptive carrier arrangement method to supplement system which is weak to intentional interference or jamming and to improve system performance against interference or jamming. We would like to analyze proposed SLM based DFT spreading OFDM system using adaptive carrier arrangement method. And we compare and analyze system performance through simulation under MTJ (multi-tone jamming) and PBJ (partial band jamming) environments.
