Side information in PAR reduced PTS-OFDM signals
Jayalath, Dhammika & Tellambura, Chintha (2003) Side information in PAR reduced PTS-OFDM signals. In 14th IEEE Conference on Personal, Indoor and Mobile Radio Communications, 2003 (PIMRC 2003), 7-10 Sept. 2003, Beijing, China.
Orthogonal frequency division multiplexing suffers from large peak-to-average power ratios (PAR). Large PAR causes undesirable effects such as signal distortion and unwanted out of band radiation. Use of partial transmit sequences (PTS) is proposed to improve the PAR statistics of OFDM signals. Phase angles of the modulated symbols are changed in PTS to reduce the PAR. The information about these changes (side information) is critical for the successful operation of PTS. However, a proper way to send side information to the receiver without affecting the optimized PAR statistics has not been reported in the open literature so far. In this paper, we present a novel scheme to insert the side information into PTS-OFDM signals without affecting the improved PAR statistics. Simulation results show that the proposed scheme does not contribute to any peak-regrowth and the hit error rate performance of the system is improved.
Impact and interest:
Citation counts are sourced monthly from and 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 downloads displays 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.
