A Novel Partial Transmitting Sequence Technique for Peak-to -Average Power Ratio Reduction in Multicarrier Transmission Systems

As an attractive technique for the reduction of the peak-to-average power ratio (PAPR) of multi-carrier transmission systems is proposed. The conventional partial transmitting sequence (PTS) combining can improve the PAPR statistics of a multi-carrier transmission systems signal. However, the optimum PTS technique requires an exhaustive search over all combinations of allowed phase factors, the search complexity increases exponentially with the number of sub-blocks. In this paper, a novel PTS based on electromagnetism-like (EMPTS) algorithm with threshold control structure is proposed to search the optimal combination of phase factor. The EMPTS algorithm not only reduces the PAPR significantly, but also decreases the computational complexity. Simulation results are conducted to demonstrate that the proposed scheme can achieve a good PAPR reduction with a better convergence rate compared with the various stochastic search techniques.
