一种宽带无线接入网中的信道分配方案

A channel allocation method for broadband wireless access network

主要研究宽带无线接入(BWA)系统中的动态信道分配技术。根据数据网络的业务流量特点,引入了新的上层业务仿真模型(PARETO模型),并且针对BWA系统的特点,提出了采用一种基于信噪比测量的动态信道分配方案。仿真结果表明,此方案可以减少系统的同频干扰,提高平均信噪比,从而提高了整个通信系统的数据吞吐量。

In this paper, the authors investigate dynamic channel allocation techniques in BWA system and introduce a new upper service model, namely PARETO model, according to the characteristics of the data network. Then the authors analyse the features of the BWA channel and put forward a kind of dynamic channel allocation scheme based on SNR measured. The experiment result indicates this technique can reduce the service hotspot and raise the data throughput of the entire communication system.
