Optimum selective mapping for PAPR reduction
2011 Wireless Telecommunications Symposium (WTS), 2011High 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

PAPR Reduction Techniques for Multicarrier Systems
2012OFDM (Orthogonal Frequency Division Multiplexing) technique has been widely adopted in many wireless communication systems due to its high data-rate transmission ability and robustness to the multipath fading channel. One major drawback of the OFDM signal is the high peak-to-average power ratio (PAPR) problem.

PAPR Reduction in Trigonometric-Based OFDM Systems
2007 Conference Record of the Forty-First Asilomar Conference on Signals, Systems and Computers, 2007A key building block in any OFDM transceiver is the Fast Fourier Transform (FFT) and its inverse. A number of researchers have recently proposed the use of the discrete cosine transform (DCT) and the discrete sine transform (DST), and their inverses as alternative modulating/demodulating bases to improve the BER performance of OFDM schemes while ...
