摘要
OFDM(正交频分复用)系统中的动态资源分配能够有效地利用有限的系统功率和频谱资源,提高系统性能,被广泛研究.本文重点讨论了单用户、多用户及多小区OFDM系统中的资源分配问题,综述了现有的研究成果,总结了热点研究方向,为以后的研究奠定了基础.
A lot of research effort has been spent on dynamic resource allocation in OFDM (Orthogonal Frequency Division Multiplexing) system so as to exploit the limited system power and scarce frequency resource, and provide significant performance gains. This paper discusses the resource allocation issues in single user,multiuser as well as multicell OFDM systems. It gives a review of current research in order to investigate future research issues.
