Abstract

One disadvantage with current OFDM systems is, the system complexity associated with FFT module, equalier, 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.
