| 摘 要： | 该文针对以OFDMA(Orthogonal Frequency Division Multiple Access)为多址接入方式的多无线电系统中用户比例公平性和系统效率问题进行了研究，提出一种联合资源分配算法，不仅保证了用户比例公平性下系统的吞吐量，还充分考虑了分配的带宽是子信道带宽整倍数的特点，对分配给每个终端的带宽进行子信道整数倍调整。最后通过仿真对比，从系统吞吐量和公平性两方面给出了算法的性能。 |

| Abstract: | A joint resource allocation algorithm is proposed to solve the problem of the proportional fairness and the system efficiency in multi-radio systems based on OFDMA (Orthogonal Frequency Division Multiple Access). The algorithm optimizes the system throughput under the fairness constraint, and considers that the allocated bandwidth should be integer times of the subchannel bandwidth. The bandwidth allocated to each terminal is adjusted according to this consideration. The performance of the proposed algorithm is evaluated by simulations in terms of the system throughput and the fairness. |
| Keywords: | Multi-radio systems Joint resource allocation Proportional fairness Integer times of the subchannel bandwidth Optimization |
