抄録(英) 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 spread OFDM system when comb type is inserted to estimate channel characteristics. So, in this paper, we apply a SLM (selective mapping) method to reduce increased high PAPR. Also, we suggest an effective method to transmit side information (SI) without additional bandwidth. DFT spread OFDM system is very weak against jamming. However so far, analysis of jamming is not almost done in DFT spread OFDM system. So, in this paper, we like to analyze and simulate the performance of DFT spread OFDM system based on SLM against jamming signal such as MTJ (multitone jamming) and PBJ (partial band jamming). And also, to remedy vulnerable shortcomings of DFT spread OFDM about jamming, we employ a FH (frequency hopping) technique.
