PAR reduction of an OFDM signal using partial transmit sequences
Tellambura, Chintha & Jayalath, Dhammika (2001) PAR reduction of an OFDM signal using partial transmit sequences. In IEEE VTS 54th Vehicular Technology Conference, 2001 (VTC 2001 Fall)., 7-11 Oct. 2001, Atlantic City, NJ, USA.
The peak-to-average power ratio (PAR) of an orthogonal frequency division multiplexing (OFDM) signal can be substantially larger than that of a single carrier system. Partial transmit sequence (PTS) combining can improve the PAR statistics of an OFDM signal. For PTS, the search complexity increases exponentially with the number of subblocks. We present a new algorithm for computing the phase factors that achieves better performance than the exhaustive binary search approach. We also investigate the effects of non-linear amplifiers on the performance of the new algorithm, including the power spectral density and in-band distortion.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
