In this book, some of the existing PAPR reduction techniques have been analyzed. After discussing the existing PAPR reduction techniques, two new PAPR reduction techniques have been proposed which are based on the existing schemes. The simulation results for the proposed techniques are compared with some of the existing techniques like, Partial Transmit Sequences (PTS), Selective Mapping (SLM), Iterative flipping and new SLM. Although all the existing techniques can reduce the Peak to Average Power Ratio (PAPR), the computer simulation results show that the Proposed techniques can offer better Peak to Average Power Ratio (PAPR) reduction performance. These proposed techniques have been named as Proposed Technique1 and Proposed Technique2 in this work. The results also show that the Proposed technique2 performs better than Proposed technique1 in terms of PAPR reduction when the numbers of subblocks in the OFDM transmitted signal increases. However, when the number of sub-blocks is...
