摘    要:MIMO-OFDM技术是实现大容量无线数据传输的一项关键技术.多用户系统中,在最大化系统资源利用率的同时保证用户间资源分配的公平性是系统设计的一个重要问题.该文首先分析了MIMO系统中最大化吞吐量的一种实现方式--脏纸编码(DPC),然后基于纳什公平性准则提出了一种用于DPC的多用户MIMO-OFDM系统中的自适应资源分配算法.仿真结果表明,该算法在损失较小系统吞吐量的前提下,很好地保证了用户间资源分配的公平性.

关 键 词:通信与信息系统  动态资源分配  纳什公平  多输入多输出/正交频分复用  脏纸编码

Abstract:MIMO-OFDM has been one of the most promising techniques for high data rate wireless transmission. In multi-user systems, how to guarantee the fairness among users while achieving large system throughput is an important issue for practical system design. In this paper, the Dirty-Paper Coding (DPC) as a new transmission technique is investigated to achieve the large throughput of MIMO systems, and a novel resource allocation algorithm based on Nash fairness is proposed for dirty-paper coded multi-user MIMO-OFDM systems. Simulation results show that the proposed algorithm can provide fair resource allocation among users, with less overall system rate loss.
Keywords:Communication and information system  Adaptive resource allocation  Nash fairness  MIMO/OFDM  Dirty-Paper Coding (DPC)
