One disadvantage with current OFDM systems is, the system complexity associated with FFT module, equaliser, etc. is almost fixed and varies little with information bit rate. In this paper, based on an innovative "layered" concept in FFT algorithms, we propose a novel OFDM system whose complexity is adaptive to the desired bit rate and system performance by exploiting transmitter diversity. Different diversity options in the transmitter and receiver are discussed, and verified in simulations.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® 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.
