摘要:
为了在OFDM的协作通信系统中能够充分利用无线频谱资源,将携能无线通信和中继技术相结合,把认知中继的子载波分为两部分(一部分用于自身的信息传输,另一部分用于主用户的数据转发),并用分支定界法优化了最大次用户网络吞吐量.实验表明,优化后的最大化次用户网络的吞吐量明显优于填充式认知无线电和下垫式认知无线电,频谱资源也得到了充分的利用.
Abstract:
In order to make full use of the radio spectrum resources in OFDM cooperative communication system, combined with wireless communication and relay technology, the cognitive relay subcarrier is divided into two parts(a part used in information transmission, the other part is used for primary user data forwarding), and the maximum throughput of subuser network is optimized by branch and bound method. Experiments show that the throughput of the optimized maximized subuser network is obviously better than that of the Overlay cognitive radio and the Underlay cognitive radio. The throughput of the subuser network is greatly improved and the spectrum resources are fully utilized.
