PEAK-TO-AVERAGE POWER RATIO REDUCTION OF OFDM SIGANLS
International Journal of Research in Engineering and Technology, 2012 Orthogonal frequency division multiplexing (OFDM) is a form of multicarrier modulation technique with high spectral efficiency and immunity to interference. Despite of many advantages the main disadvantage of OFDM is that the time domain of OFDM signal which is a sum of subcarrier sinusoids leads to high Peak-to-Average power ratio (PAPR).

New peak-to-average power-ratio reduction algorithms for multicarrier communications [PDF]
2003 IEEE Pacific Rim Conference on Communications Computers and Signal Processing (PACRIM 2003) (Cat No 03CH37490) PACRIM-03, 2003 Two new peak-to-average power-ratio (PAPR) reduction algorithms for passband multicarrier systems are deduced by applying optimization to modulation constellations. The associated optimization problem can be solved by two different methods, namely, the second-order cone programming method and the least-pth unconstrained optimization method.
