摘要
Abstract
In order to lower the complexity of PAPR suppression techniques based on the partial transmit sequences(PTS) algorithm,research on the relevance between the positions of top highest values in OFDM time-field signal and those of top highest values through PTS algorithm is conducted.On the basis of the research,a simplified algorithm in which the sampled data replace the original data on searching for the optimized phase agent series is proposed.By the new algorithm,adopted data is much less than the original data,and the calculating complexity of PTS decreases greatly.The simulation demonstrates that the new algorithm can reduce the data amount by 50% while the performance loss ranges only from 0.2 dB to 1 dB.关键词
