Abstract :
In this paper, we investigate the problem of resource allocation with fairness constraints for OFDMA distributed antenna system (DAS). We formulate this problem as a binary integer programming problem, and transform it into a generated directed graph with the linear optimal distributed method to solve. Some simulation results compare the proposed algorithm with a given heuristic algorithm for purpose of verifying its performance. Consequently, other simulation results are provided to show that DAS outperforms the conventional central multi-antenna systems.
