宽带无线频谱分配建模研究

Study on the Distribution Modeling of the Broadband Wireless Spectrum

随着无线通信的发展,研究如何提高频谱利用率的方法是必然趋势。本文将具有不同特性的静态频谱,竞拍频谱以及动态频谱进行联合分配研究。对频谱可用性特性指标和基于M-LWDF算法的服务质量指标进行了详细的分析说明。并提出了一种有序匹配算法。该算法通过频谱可用性和服务质量指标的有序对应匹配,实现多种频谱资源相结合环境下的频谱分配方案。并通过与随机分配、先静态、后动态的分配方案进行对比,用MATLAB仿真工具验证了该算法在平均总速率、平均失败次数等方面的优越性。

With the rapid wireless communication technology development, research on improving the spectrum utilization is a growing trend. This paper studied spectrum allocation method with the static spectrum,auction spectrum and dynamic spectrum. It explained the spectrum availability of spectrum, which covers signal-to-noise ratio, price and so on. It also analyzed the request of service based on the algorithm of M-LWDF. This paper put an orderly matching algorithm based on supporting the quality of service. It used MATLAB to prove the advantage of the average numbers of failure and the average total rate compared with the RAN and CHU.
