摘要：

<正>High Peak-to-Average Power Ratio（PAPR）is one of the major drawbacks of Orthogonal Frequency DivisionMultiplexing（OFDM）systems.This paper presents the structures of the particular bit sequences leading to the maximumPAPR(PAPRmax)in Carrier-Interferometry OFDM（CI/OFDM）and Pseudo Orthogonal Carrier-Interferometry OFDM（PO-CI/OFDM）systems for Binary Phase Shift Keying（BPSK）modulation.Furthermore,the simulation and analysisof PAPRmax and PAPR cumulative distribution in CI/OFDM and PO-CI/OFDM systems with 2048 sub-carriers are pre-sented in this paper.The results show that the PAPR of OFDM system with large number of sub-carriers reduced evidentlyvia CI approaches.
