环境友好型联合水下信道和功率分配算法

Environment-friendly jointly power and channel allocation algorithm in underwater cognitive acoustic networks

在水下认知声学网络中哺乳动物的自然声学系统和人类用于探测监控的人工声学系统共存,同一水域的两种系统共享频谱资源,为了减少人工声学系统对海洋动物的影响,文中提出了一种水下环境友好型的以网络容量最大化为目的的联合信道和功率分配算法。实验测试了不同场景下系统容量的变化和用户的信道功率分配。

The natural acoustic system used by marine mammals and the artificial acoustic system used by humans coexist in the underwater cognitive acoustic networks. They share the spectrum when they are in the same waters. To reduce the impact of the artificial acoustic system on the natural acoustic system, this paper proposed a jointly optimizing power and channel allocation algorithm targeting capacity maximization of a environment-friendly underwater acoustic networks. The change of the system capacity and the power and channel allocation of among users were tested in the simulation.
