PTS Sub-optimum Improved Algorithm Reducing PAPR of OFDM System

For the problem of high PAPR in the Orthogonal Frequency Division Multiplexing (OFDM) system, Partial Transmission Sequence (PTS) algorithm is an effective method. However, the main problem of PTS algorithm is how to reduce computing complexity when searching the optimum phase. In this case, this paper brought about the Adaptive Partial Transmission Sequence (APTS) algorithm to reduce computing complexity. Based on the iteration in the APTS algorithm, the algorithm has completed when the computed PAPR is smaller than the set threshold value. The simulation results indicate that the adaptive PTS algorithm has a better performance than PTS algorithm in terms of the computing complexity. In other words, the computing complexity is smaller.
