摘要

本文提出了一种基于天线维数和频率维数简化的、兼顾公平性的实时子载波分配算法。我们的目标是通过了解所有用户的信道特性，公平地为每个用户分配子载波，并在比例速率约束下最小化总发射功率的要求下降低计算复杂度。仿真结果表明，该算法在子载波分配方面具有公平性，优于无天线维数的MIMO-OFDM多用户传输，且显著降低了计算复杂度。

A novel two-dimension simplified subcarrier allocation with fairness for multiuser MIMO-OFDM transmission

In this paper, a real-time subcarrier allocation algorithm with fair consideration is proposed based on simplification at both antenna dimension and frequency dimension. By knowing the channel characteristic of all users, our goal is to assign subcarriers to each user fairly and reduce computational complexity with requirement of minimizing the overall transmit power subject to the proportional rate constraints. Simulation results show that our proposed algorithm presents fairness in subcarrier allocation and outperform none antenna-dimension employed multiuser MIMO-OFDM transmission with significant computational complexity reduction.
