Improved PTS Algorithm for Optimizing PAPR of OFDM System

The high Peak-to-Average Power Ratio must be taken into account and resolved in putting OFDM system into practice. Aiming at the problem, PTS algorithm and its improved algorithms are well studied. With consideration of the computational complexity, a novel algorithm based on combined sub-block division of the iterative searching algorithm is proposed. The simulation results show that the proposed algorithm is practicable and could achieve good PAPR reduction and low computational complexity.
