Abstract

Orthogonal Frequency Division Multiplexing (OFDM) has recently been focused on in high-data-rate wireless communication research. But the high Peak-to-Average Power Ratio (PAPR) is one of the main obstacles to limit wide applications of OFDM. In this paper, based on the thorough research of selective mapping (SLM) and partial transmit sequences (PTS), the modified SLM schemes with the Riemann matrix are proposed. In the proposed schemes, it is not needed to exchange side information between transmitter and receiver. And it is shown that better PAPR reduction performance is achieved as compared to the basic SLM by Monte Carlo simulations.
