Abstract:

PTS (Partial Transmit Sequence) is an effective algorithm for the reduction of the high peak-to-average ratio (PAPR) of OFDM signal.But its application is limited for its high computational complexity.This research on the PTS algorithm covers IPTS,sliding window search PTS,Sub-block combined division PTS,Hadamard-PTS,m-sequence PTS,pso-PTS,and their algorithm performances are carried out.Then two PTS syncretic algorithms are proposed to improve the performance.The simulation results show that the syncretic algorithm is of low computational complexity and can restrain the high PAPR effectively.

Key words: OFDM;PAPR;PTS;syncretic algorithm
