Flipping PTS-OFDM System without Side Information

摘要：

In this letter, we propose a novel scheme to reduce the PAPR of OFDM signals. It combined the channel estimation in OFDM system based on comb-type pilots and Flipping PTS algorithm. At the sender we insert comb pilot independently and evenly into every partitioned sub-blocks after partition. The side information of Flipping PTS algorithm as one part of the channel frequency response is transmitted. We can achieve Flipping PTS algorithm without SI. Simulation results show that performance of the new algorithm without SI is worse than the algorithm with SI. However, it reduced PAPR, increased of the data rate.
