An Accurate Performance Analysis of an FFR Scheme in the Downlink of Cellular Systems Under Large-Shadowing Effect
The authors address the problem of analyzing the performances of interference-limited cellular networks in large-scale shadowing environments. Focusing on the Fractional Frequency Reuse (FFR) framework, they examine how to optimally assign mobile users in a cell either to the full frequency reuse part or to the orthogonal part of the FFR band. Instead of using traditional Monte Carlo simulations, which do not provide sufficiently accurate results under important shadowing, they propose a fast and accurate numerical method. They consider a fast-fading environment and they use the ergodic capacity as the performance measure.
