The research work which is presented in this book consists of initiating power, subcarrier allocation in a dynamic FFR based scheme designed for multi-cell OFDMA networks and to enhance the throughput of all center users in bandwidth hungry borrower cells (overloaded cells) which was previously degraded by original FFR-3 scheme as a result of partitioning of system bandwidth into center and edge bands respectively. This book provide a literature study, development of the framework and the simulation scenarios, programming(Matlab), visualization, as well as performance evaluation and analysis. The scheme presented in this book is load adaptive, decentralized and time efficient and can be activated on any base station according to its load conditions. The presented scheme will be helpful for researcher and students in the next generation mobile networks design and modeling such as 3GPP LTE and WiMAX (IEEE 802.16x).
