摘　　要：在密集的无线通信网络中,在正交信道上传输信息的用户竞争有限的频谱资源会产生严重的互扰。为了突破正交信道间隔的约束,研究者提出了部分重叠信道(Partially Overlapping Channel,POC).它能够显著提升可用信道数目,提高频谱资源利用率。然而,现有关于POC的研究大多假设信道带宽固定,仅仅通过切换信道的方式躲避恶意干扰的攻击,形式较为单一。本文考虑运用信道重构技术来处理抗干扰信道选择问题,优化目标为最大化网络吞吐量。首先,同时对用户受到的内部互扰和外部干扰进行建模;其次,针对用户间信息可交互和无交互两种情况,分别提出基于最优响应的带宽重构抗干扰算法和基于随机自动学习机(Stochastic Learning Automata,SLA)的带宽重构抗干扰算法。最后,通过和固定带宽模式的对比可以发现,带宽重构模式的信道选择抗干扰方法能够获得更大的网络吞吐量,具有更优的性能。In dense wireless communication networks,competition for limited spectrum resources by users transmitting information over orthogonal channels can cause serious mutual interference.In order to break the constraint of orthogonal channel spacing,a POC(Partially Overlapping Channel) scheme is proposed,it can significantly increase the number of available channels and improve spectrum resource utilization.However,most of the existing research on POC usually assumes that the channel bandwidth is fixed,only by switching and the attack is only used to avoid malicious interference attacks,the form is relatively single.The channel reconstruction technique is considered and used to deal with anti-jamming channel selection problems,and the optimization goal is to maximize network throughput.Firstly,the internal interference and external interference experienced by the user are modeled at the same time.Then,for the information interaction and non-interaction between users,the bandwidth reconstruction anti-jamming algorithm based on optimal response and the bandwidth reconstruction anti-jamming algorithm based on SLA(Stochastic Learning Automata) are proposed respectively.Finally,the comparison with the fixed bandwidth mode indicates that the channel selection anti-jamming method with bandwidth reconstruction mode can obtain greater network throughput and has better performance.
