| Title: | Peak-to-Average Power Ratio Reduction in OFDM: Blind Selected Mapping for PSK Inputs | ||
| Authors: | G. Tong Zhou, Georgia Institute of Technology, United States | ||
| Abstract: | Orthogonal Frequency Division Multiplexing (OFDM) is a modern transmission format that has gained much popularity in the past decade. However, a serious drawback of OFDM is the high peak-to-average power ratio (PAR) of its time domain waveforms. Selected mapping (SLM) is a distortionless technique that has good PAR reduction capability; the biggest limitation of SLM however, is the need to transmit side information. In this paper, we assume constant modulus (i.e., phase shift keying - PSK) inputs and propose a novel technique that allows us to carry out SLM without having to transmit any side information and without causing any distortions. | ||
