The Dynamic Spectrum Access (DSA) system is considered an effective solution for the spectrum scarcity problem since it gives an opportunity for Secondary Users (SUs) to share Primary Users (PUs) spectrum resources. Therefore, in order to build an effective DSA system, there are two main constraints: firstly, SUs should not cause any harmful interference to the PUs. Secondly, the DSA system should make interference coordination among SUs. In this paper, a Multi-Armed Bandits (MABs) learning algorithm is used to optimize the DSA system to enhance the whole system performance. Using simulation, results show that the MABs algorithm could learn the environment and achieved the maximum allowed average data rate while keeping an eye on the interference threshold with PUs and other SUs. |
