An Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...

متن کاملM-ary Chaotic Sequence Based SLM-OFDM System for PAPR Reduction without Side-Information
Selected Mapping (SLM) is a PAPR reduction technique, which converts the OFDM signal into several independent signals by multiplication with the phase sequence set and transmits one of the signals with lowest PAPR. But it requires the index of the selected signal i.e. side information (SI) to be transmitted with each OFDM symbol. The PAPR reduction capability of the SLM scheme depends on the se...
متن کاملDistributed Coding Scheme for Multi-view Video through Efficient Side Information Generation
In this paper, a distributed image coding scheme for multi-view video through an efficient generation of side information is proposed. A distributed video coding technique corrects the errors in the side information, which is generated with the original image, by using the channel coding technique at the decoder. Therefore, the more correct the generated side information is, the better the perf...
متن کاملPAPR Reduction in MIMO-OFDM Systems using Modified PTS and SLM without Side Information
Limiting the peak to average power ratio (PAPR) to an acceptable level is of great importance to MIMO-OFDM systems. Otherwise, a series of undesirable interventions due to the large PAPR is encountered, such as inter-modulation distortion and outof-band radiation. In this paper, we have proposed a modified partial transmit sequence (PTS) scheme and implemented a new selected mapping (SLM) techn...
