Abstract
OFDM has a high peak to average power ratio ( PAPR ), when the signal PAPR over power amplifier ( HPA ) linear dynamic range, will introduce nonlinear distortion, affecting the signal transmission performance. In order to overcome the defects, OFDM need to adopt the corresponding PAPR suppression technique, the signal amplitude changes of power amplifiers in the allowable range. This paper presents a new partial transmit sequence algorithm ( PTS ), double phase sequence reversal threshold algorithm, and simulation results show that the new algorithm on the PAPR suppression effectiveness, search depth of T, the inhibition on PAPR performance.
