Abstract :
High Peak-to-Average Power Ratio (PAPR) is a major drawback of multi-carrier transmission such as Orthogonal Frequency Division Multiplexing (OFDM). Various techniques have been proposed to reduce PAPR, among them SeLective Mapping (SLM) is a non-distortion method that incurs little loss in efficiency. In this paper, the criterion for optimum selective mapping is investigated. A parametric phasing scheme that can provide optimum SLM is introduced for low cost implementation for both transmission and reception.
