Investment of Cyclic Prefix to Reduce the Peak-to-Average Power Ratio and Recover Original Phases Blindly

When dealing with the phenomenon of unexpected high peak-to-average power ratio (PAPR) caused by multicarrer techniques, it is rarely to find a proposed solution that addresses most important challenges together, are; reducing PAPR, achieving performance identical, mostly, theoretical curve and reasonable level computational complexity. This paper presents new proposal able achieve these three criteria together as following. First, PAPR curves through easy development in selective mapping (SLM) structure. Second, identifying original transmitted phase block taking advantage cyclic prefix structure its mechanism, without any explicit side information, while maintaining system performance. Lastly, achievements were obtained at low complexity comparing traditional methods SLM reduction schemes. method referred as; Injected Extracted Short-SLM from Cyclic Prefix (IES-SLM-CP). The appropriate short sub-block injected specific locations CP, receiver side, this can be extracted CP reconstruct whole block.
