摘要：
In OFDM system high PAPR leads to BER degradation and nonlinear distortion. A joint algorithm based on PTS (Partial Transmit Sequence) and CE (Constellation Extension) was studied to solve the problem in this paper. The output of iterative-shifting linear searching PTS was firstly transformed by FFT and then input to the constellation extension module to inhibit the system PAPR. The simulation results show that PTS-CE joint algorithm not only can inhibit PAPR more effectively, but also reduce the complexity of the algorithm and the system implementation.
