Abstract
In this letter, we propose a novel scheme to reduce the PAPR of OFDM signals, and its key idea is that the side information of partial transmit sequence is considered as a part of channel frequency response. Therefore, the proposed scheme does not need to reserve bits for submitting side information, resulting in an increase in the data rate. Furthermore, we propose a novel pilot arrangement, in which pilot tones are independently inserted into each subblock. Simulations show that the proposed scheme with the novel pilot arrangement could offer good performances of bit error rate and PAPR reduction.Keywords
