认知无线网络中具有保护间隔的非时隙载波侦听多址接入方案的性能分析(英文)

Performance Analysis of Unslotted CSMA with Guard Time in Cognitive Radio Network

提出了在认知无线网络中具有保护间隔的非时隙载波侦听多址接入方案,并对其性能进行了分析.通过概率分析方法得出非授权用户的吞吐量及干扰率等认知无线网络的性能指标,数值结果显示本方案具有较好的性能.

We proposed an unslotted carrier sense multiple access（CSMA） with guard time in single channel cognitive radio network and analyzed its performance.Analytically the performance measures such as the throughput of SUs and the interference ratio were obtained.Numerical results show that unslotted CSMA with guard time has good performance than that of without guard time.
