摘要

本文研究了OFDMA分布式天线系统中具有公平性约束的资源分配问题。将该问题形式化为二进制整数规划问题，并将其转化为生成的有向图，用线性最优分布方法求解。仿真结果将所提出的算法与给定的启发式算法进行了比较，以验证其性能。仿真结果表明，该系统优于传统的中央多天线系统。

Radio resource allocation for multiuser OFDMA distributed antenna systems

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.
