SER analysis of PTS based techniques for PAPR reduction in OFDM systems
TL;DR: CCM-P TS method almost has the same PAPR reduction capability as M-PTS, but its SER performance is better than M-pTS and uses a simpler method to decode the data symbols.

A novel quadrilateral companding transform for PAPR reduction in OFDM systems
TL;DR: The proposed companding scheme transforms the Rayleigh distributed probability distribution function of original OFDM signal magnitude into quadrilateral shape PDF, hence the name “Quadrilateral Companding Transform (QCT)”; the proposed method provides better design flexibility to achieve an effective trade-off between PAPR reduction capability and bit-error rate (BER) performance.

TL;DR: The proposed algorithm is capable of reducing the paging cost approximately by a factor of two for maximum subarea area size 6 i.e. approximately half of the cells are required to be paged.

- 01 Dec 2010
TL;DR: A new PTS technique is proposed which involves a mapping of quaternary data over concentric circles and allows simplified decoding and provides better SER performance with good PAPR reduction.

Generalized M-2M Mapping Scheme for SLM and PTS Based OFDM Systems Without Side-Information
TL;DR: A new mapping scheme, named “2M-2M Mapping scheme” is proposed for SLM and PTS based methods to completely eliminate the requirement of SI at the receiver, which is scalable and provides good PAPR reduction capability with consistent BER performance.
