Peak power reduction of space-time coded OFDM signals
Jayalath, Dhammika & Athaudage, Chandranath R. N. (2004) Peak power reduction of space-time coded OFDM signals. In IEEE Eighth International Symposium on Spread Spectrum Techniques and Applications, 2004, (ISSSTA 2004)., 30 August - 2 September 2004, Sydney, Australia.
Peak power reduction in space-time coded orthogonal frequency division multiplexing (OFDM) systems is a challenging task. Most of the current peak power reduction schemes reduce the peak power by manipulating the signal at the final IDFT process. However, in the case of space-time coded OFDM, any processing at this stage would violate the space-time code structure, making its detection at the receiver impossible. The paper shows that selected mapping (SLM) reduces the peak power of space-time coded OFDM signals without violating the space-time code. Reduced peak power of the OFDM signal relaxes the strict dynamic range requirements of the transmitter.

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.
