Interference avoidance using dynamic frequency reuse for LTE-A system

To meet the increasing demand for spectrum in communication system, Long Term Evolution (LTE) system has been proposed. It al-lowed users to use a new and much wider spectrum comparing to the other previous technologies. To utilize the full capacity of the LTE system Frequency Reuse (FR) has been ad...
