    Enhanced PAPR reduction and channel estimation techniques in multi-carrier wireless communication system

    Enhanced PAPR reduction and channel estimation techniques in multi-carrier wireless communication system by Ali Kareem, Nahar

    Published 2016
    “…Besides, the CE scheme based on a Local Search Algorithm was suggested. The simulation results of RPS were compared with various PAPR reduction schemes, such as selective mapping (SLM) technique and Partial Transmission Sequence (PTS), and furthermore, different phase shifts with slight computational complexity had been analyzed. …”
