Studying Optimal Design of Strict Fractional Frequency Reuse in OFDMA Cellular System
Mahmoud Nagieb, Mona Shokair, Waleed Saad · International Journal of Computer Applications · 2015
The key characteristic of a cellular network is the ability to reuse frequencies to increase both coverage and capacity.Fractional frequency reuse (FFR) is considered to be an efficient inter-cell interference coordination technique wellsuited for OFDMA based on wireless communication networks where the cells are partitioned into spatial regions with different frequency reuse factors.In this paper, evaluating strict FFR which represents a type of FFR deployments is presented with four different system models by changing the inner-cell shape for each model.System simulations are used to compare and evaluate the effect of changing the inner-cell shape based on strict FFR performance which performed using dense Monte Carlo simulations.In addition, the effects of some system model parameters are discussed.
