    Energy efficiency comparison of IICM and Clipping using real power amplifier
    (University of Oum El Bouaghi, 2021) Merah, Hocine; Mecheri, Belkacem; Tahkoubit, Khaled
    Peak-to-Average Power Ratio (PAPR) is an important parameter in digital communications. Furthermore, 5G Communication Systems will be based on the new multicarrier modulation schemes. Hence, it is desirable to investigate the problems of PAPR in 5th generation communication systems. In this paper, first a detailed introduction of multicarrier modulation and PAPR problem are given. Than we compared two PAPR reduction methods : Iterative Invertible Clipping Method (IICM) and clipping with filtering method in terms of Error Vector Magnitude (EVM) for the same PAPR value. The simulation results shows that there is a gain of 1dB between the two methods.
