利用导频降低峰均值比算法的研究
Algorithm of using pilot frequency to reduce PAPR
摘要
Abstract
The partial transmit sequence(PTS)method is one of the most effective methods to reduce the peak⁃to⁃average power ratio (PAPR) in orthogonal frequency⁃division multiplexing (OFDM) system. In comparison with the conventional PTS (C⁃PTS),the insertion of pilot frequency sequence can reduce the PAPR better. The pilot signal with cyclic shift is adopted in this paper. The pilot frequency signal and data signal are divided into the subblocks respectively,and then the pilot frequency subsequences are inserted into the data subblocks respectively to generate more sequences waiting for selection through feedback and cyclic shift and reduce the PAPR better. The simulation results show that the proposed method can reduce the PAPR effec⁃tively,and the performance of its bit error rate(BER)is as same as that of C⁃PTS method.关键词
