Abstract
In this paper, a new PAPR reduction method using correlation of input data sequence is proposed in order to overcome the serious drawbacks, such as necessity of side information transmission or increase of system complexity and calculation. A new PAPR reduction method can be classified into method 1 and method 2. Method 1 reduces the correlation between the smallest sub-sequence and neighbor smallest subsequence. To consider the own correlation in detail, the method 1 reduces two cases of correlation between neighbor smallest sub-sequences and neighbor largest sub-sequences. Method 1 and method 2 has about 0.5-0.8 dB and 1-1.2 dB PAPR reduction effect respectively. If more detailed process is considered, we can achieve better PAPR reduction performance
