ABSTRACT
This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book focuses on the development of various link adaptation mechanisms for Orthogonal frequency-division multiple access (OFDMA)-time division duplex-based two-hop cellular networks with fixed relays. It proposes an end-to-end link adaptation and selection method for wireless relay networks. The book also focuses on the development of a scheduler for implementation in two-hop cellular networks. It analyses the end-to-end maximum achievable rate of various relaying schemes. The book also analyses the inefficiency of having the same Medium Access Control-Protocol Data Unit size over all the links constituting a multi-hop wireless communication system. It presents the synchronization issues for OFDM-based wireless relay networks. The book then analyses the time and carrier frequency offset issues and the complexity of various cooperative diversity implementations for Mobile Stations.
