An algorithm for PAPR reduction by SLM technique in OFDM with hadamard matrix row factor

This paper is concerned with the performance improvement of PAPR reduction of orthogonal frequency division multiplexing (OFDM) using selective mapping based design. Note that OFDM is one of the most proficient multi-carrier transmission scheme which has been implemented in long term evolution (LTE) downlink. However peak to average power ratio (PAPR) is the main problem with OFDM, therefore in this paper we have proposed a reduction procedure of the PAPR by using selective mapping technique. Here we have used hadamard matrix row factor as it´s phase sequence to investigate the reduction of the PAPR. Our results show that the proposed method with the hadamard matrix row factor significantly enhances the PAPR performance.
