As the research for future fourth generation (4G)mobile communication systems has been launched worldwide in major companies and academic institutions, forward-thinking professionals are striving to gain a thorough understanding of the cutting-edge technologies and design techniques that will make these systems work. This unique new book helps you do just that. It provides you with a comprehensive introduction to multicarrier techniques for 4G mobile communications with a special focus on the analytical aspects. Radio channel characteristics and phenomena are explained along with discussions on the advantages and disadvantages of OFDM scheme. You get in-depth explanations of new multicarrier-related techniques, MC-CDMA, research on several 4G systems and a look at several problems to be overcome regarding these systems.

This authoritative reference is designed to help you better understand the concept and detail of the ODFM scheme and how to carry out theoretical analysis on the performance of transmission systems in radio channels. The book shows how OFDM has been successfully adopted as a modulation scheme in communications systems and broadcasting systems such as ADSL, wireless LANs, DVB-T. Moreover, it looks at OFDM as a promising modulation scheme in future 4G mobile communication systems.
