High capacity high spectral efficiency transmission techniques in wireless broadband systems

Abstract

The objective of this thesis is to look into some potential techniques to achieve the high capacity high spectral efficiency transmission in the wireless broadband systems, as the next generation wireless communication (NextG) urges on high quality high data rate transmissions.Some advanced techniques to improve the spectral utilization of the wireless communication systems is discussed, and a literature summary in these areas is provided. Some minor contributions on turbo coding and quantifying the achievable diversity gain in multiuser OFDM systems are given in Chapter 3.More major contributions follow with two different methodologies: one is to improve the spectral efficiency with fixed spectrum, while the other one is dynamic spectrum assignment. Both, however, aim to improve spectral utilization.
