| Publisher Description: In recent years, relay systems have become a subject of intensive research interest as it has become evident that they can improve performances and extend the coverage area of wireless communication systems. Special attention has been dedicated to relay systems since the proposal appeared for their implementation in mobile cellular systems. Numerous studies conducted after that proposal have enabled the incorporation of OFDM based relay systems in the accepted standards for IMT-Advanced systems. Nowadays, these ongoing studies aim to define new solutions for performance improvement of the standardized OFDM relay systems for cellular networks, and one of the interesting solutions is the implementation of a subcarrier permutation (SCP) at the relay (R) station. OFDM Based Relay Systems for Future Wireless Communications presents comprehensive research results in analyzing behavior and performance of the OFDM based relay systems with SCP. Dual-hop relay scenarios with three communication terminals and no direct link between the source (S) and the destination (D) have been analyzed as they are compliant with the accepted solutions for IMT-Advanced systems. This book includes performance analysis and performance comparison of OFDM based: - amplify-and-forward (AF) relay systems with fixed gain (FG), - amplify-and-forward (AF) relay systems with variable gain (VG), - decode-and-forward (DF) relay systems, each including two SCP schemes known to maximize the system capacity and/or improve the bit error rate (BER) performances. Performance comparisons have enabled definition of optimal solutions for the future wireless communication systems in a given conditions, and for the given optimality criteria. OFDM Based Relay Systems for Future Wireless Communications is ideal for academic staff and master/research students in area of mobile communication systems as well as for the personnel in communication industry. |
