Abstract

High Peak-to-Average Power Ratio (PAPR) is a major drawback of Orthogonal Frequency Division Multiplexing (OFDM) based communications systems. Many methods for PAPR reduction have been reported in the literature. They include popularly used Selective Mapping (SLM) and Partial Transmit Sequences (PTS) techniques. Although these two methods reduce PAPR quite well, their implementation cost is relatively high. In this paper, Symbol Alphabet Modifier Matrix (SAM) is proposed to jointly alter the phase and amplitude values of the original symbols in the alphabet. This framework utilizes only one FFT/IFFT operation pair for transmultiplexing of symbols without any side information. The merit of the proposed method to reduce PAPR for four cases without BER degradation along with its implementation simplicity is shown in the paper.
