摘 要：随着无线通信需求的增加，有限的频谱成为一项关键挑战。传统上，某些频段是为特定目的而分配的，并且只能由被许可的用户访问，该策略导致频谱利用率低下。虽然认知无线电网络可以缓解频谱稀缺问题，但节点仍然需要争夺资源，因此频谱的公平分配是一个重要的考虑因素。我们希望找到一种认知无线电网络资源分配的公平方法，并达到吞吐量和公平性的均衡性能。

Abstract：With the increasing demand of wireless communication，limited spectrum becomes a critical challenge. Traditionally，certain bands are allocated for specific purpose，and can only be accessed by licensed users. This policy leads to the inefficiency utilization of spectrum. Although cognitive radio network can alleviate spectrum scarcity problem，nodes still need to contend for resources，hence fair allocation of spectrums is an important consideration. We hope to find a method for cognitive radio network fair resource allocation and to reach a balanced performance of throughput and fairness.
