摘  要：移动无线通信的主要限制在于有限的频谱资源。而无线资源管理（Radio Resource Management，RRM）技术恰是使频谱资源能够得到有效利用的重要途径之一，灵活有效的无线资源管理能力是系统性能提高的关键。通过对经典算法的研究，提出一种结合比较机制及整比特资源分配的改进算法。仿真结果表明，改进算法在满足系统服务质量（QOS）要求的前提下，相对于经典算法使频谱资源的利用率有较大提高，且复杂度有所下降。

Abstract: Mobile wireless communications is a major constraint of limited spectrum resources. The radio resource management (Radio Resource Management, RRM) techniques appropriate to make efficient use of spectrum resources can be one of the important ways, flexible and efficient radio resource management is the key to improving system performance. By the classical algorithm, proposed a bit more resource allocation mechanism and the improvement of the whole algorithm. Simulation results show that the improved algorithm to meet the system quality of service (QOS) requirements of the premise, as opposed to the classic algorithm so that the spectrum resource utilization has improved greatly, and complications have to descend.
