Abstract :
The paper focuses on OFDMA Subcarrier Allocation algorithms for multiple users in a multi-cell scenario. The algorithms are distributed and either exploit measured interference per subcarrier feedback for all subcarriers (DRA algorithm) or they limit this feedback to the best subcarriers (Minimum Feedback DRA algorithm). These algorithms will be also compared with a Random Allocation Algorithm that is combined with a Fractional Frequency Reuse pattern to show the related trade-offs between performance and complexity.
