In this thesis, three low-complex papr reduction schemes for ofdm systems are proposed all the proposed schemes can be considered as modified versions of the conventional slm scheme, which can significantly reduce high papr of ofdm signals with no distortion in the first proposed scheme,. Mimo-ofdm systems lies in a prohibitively large peak-to-average power ratio ( papr) of the transmitted signal on each antenna antennas and 256 ofdm subcarriers are considered where 56 of which are unused and allocated for papr reduction reduction for multicarrier modulation”, phd thesis stanford. This thesis aims to encourage use- ability of the ofdma scheme in the ul scenario by making an attempt to reduce the papr at the power allocation stage it has been shown in [14,15] that the power alloca- tion in frequency domain ( before inverse discrete fourier transform (idft) operation) creates high peaks in ofdm.

Papr and ici reduction techniques for ofdm based satellite communication systems emad al-dalakta newcastle university newcastle upon tyne, uk a thesis submitted for the degree of doctor of philosophy june 2012. This thesis focuses mainly on papr reduction of ofdm systems by using companding, partial transmit sequence (pts) and selected mapping schemes ( slm) we have proposed a quadrilateral companding transform (qct) to reduce the papr of ofdm signal it transforms the original distribution function.
