摘要

文章介绍了降低OFDM（正交频分复用）系统PAPR（峰均功率比）的各种技术

对PTS（部分传输序列）技术进行了改进

提出了部分相关-PTS方法。该方法的基本思想是经过基带调制数据分割之后

使得除第一个数据块之外的其他每一个数据块分别与第一个数据块做互相关运算

然后按照传统PTS方法继续处理部分相关的数据子块。在接收端

根据每一个子块（第一个子块除外）与第一个子块互相关值的正负来判断该子块所乘的旋转相位

无需传输边带信息就可以恢复出原始信号。仿真结果验证了该方法的有效性。

Abstract

This paper introduces various technologies for the reduction of the Peak-to-Average Power Ratio（PAPR）of Orthogonal Frequency Division Multiplexing（OFDM）systems

modifies the conventional Partial Transmit Sequence（PTS）technology and proposes a partial-correlation-PTS method.The fundamental idea of this method is that after the original modulated frequency domain signals are divided into several data blocks

every other data block than the first one does cross-correlation calculation with the first data block and then continue to handle partial-correlation data subblocks in accordance with the conventional PTS method.At the receiver end

the multiplied rotation phase of each data subblock except the first one is decided according to the positive or negative property of the cross-correlation value of that subblock with the first data subblock.Thus the original signals can be recovered without transmitting sideband information.The effectiveness of the partial-correlation-PTS method is verified by the simulation results.
