RADIO RESOURCE ALLOCATION FOR MULTIUSER OFDMA DISTRIBUTED ANTENNA SYSTEMS

摘要：

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.
