Analysis and design of SLM based DFT spreading OFDM system for active anti-jamming system
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 of pilot is exploited to estimate channel characteristics effectively. So, in this paper, we apply a SLM (selective mapping) method to DFT spreading OFDM system to reduce increased PAPR characteristics. And we suggest an effective method to transmit side information without additional bandwidth. Also, we propose an adaptive sub-carrier allocation method to improve system performance against interference or jamming. We would like to analyze proposed SLM based DFT spreading OFDM system using adaptive sub-carrier allocation method. And we compare and analyze system performance through simulation under multi-tone jamming (MTJ) and partial band jamming (PBJ) environments.
