Analysis of Hybrid PAPR Reduction Methods of OFDM Signal for HPA Models in Wireless Communications
IEEE Access, 2020 Orthogonal Frequency Division Multiplexing (OFDM) suffers from a high Peak-to-Average Power Ratio (PAPR). Designing a High Power Amplifier (HPA) with high PAPR is not a wise technique as it roots the amplifier to operate in a non-linear region which is ...
