Lin Kaicheng, Ming Jin, Ming He · 2023
Underlay dynamic spectrum access (DSA) has powerful effectiveness and efficiency for sharing radio spectrum among DSA users. But two fundamental issues have to be addressed: 1) avoiding harmful interference to Primary User (PU), 2) enabling effective transmission and coordinating interference with other Secondly User (SU). To solve the aforementioned issues, we propose a novel channel access and power control algorithm, which named Parallel Action Network Structure (PANS) Deep Double Dueling Q-Network (D3QN). Additionally, We enable SUs flexibly determine whether to perform single-channel transmission or have the opportunity for dual-channel transmission based on the current state. With the support of the two innovations mentioned above, SUs can independently select channels and control transmission power, further more improve their throughput.The numerous simulation results demonstrate the effectiveness and reliability of the proposed algorithm.
