PAPR Reduction in OFDM Via Separation of Complex Baseband Signal

OFDM system is the stronger base for the future wireless communication. The one with the lowest Peak to Average Power Ratio (PAPR) among these OFDM signal sequences are selected for transmission. One major disadvantage of OFDM is the high Peak-to-Average Power Ratio (PAPR). One investigated technique SeLected Mapping (SLM) is PAPR reduction techniques for Orthogonal Frequency Division Multiplexing (OFDM). By analyzing separation of complex baseband signal in this paper, the authors proposed a Modernize SLM algorithm (MSLM) scheme to reduce the PAPR by using the complex signal to separate into real & imaginary parts and use as an individually phase sequence multiply real part as well as imaginary part of complex signal.
