摘要

本文考虑了一个基于正交频分多址(OFDMA)的系统，并研究了将满足导向资源分配(SORA)算法与正交随机波束形成(ORB)相结合的好处，该算法旨在最大化系统中满意用户的数量，正交随机波束形成提供空间复用增益，具有低计算复杂度，低信令需求和对用户设备的高透明度。我们的调查表明，结合SORA和ORB可以在吞吐量和用户满意度方面获得可观的收益。

Joint Opportunistic Beamforming and Subcarrier Assignment for Maximization of User Satisfaction in OFDMA Systems

In this paper, we consider a system based on Orthogonal Frequency Division Multiple Access (OFDMA) and investigate the beneﬁts of combining the Satisfaction Oriented Resource Allocation (SORA) algorithm, which aims at maximizing the number of satisﬁed users in a system, and Orthogonal Random Beamforming (ORB), which provides spatial multiplexing gains and has low computacional complexity, low signaling demands, and high transparency to the User Equipment. Our investigations have shown that considerable gains in terms of throughput and user satisfaction can be achieved by combining SORA and ORB.
