Abstract
The present disclosure provides a spectrum access method and system using prior knowledge-based double-action reinforcement learning, and belongs to the technical field of electromagnetic spectrum. The method includes evaluating and screening prior knowledge, initializing a Q-table, and confirming a current state; and performing Q-learning by: firstly, decomposing an action space into two dimensions with an action in one dimension defined as a channel chosen by an agent, and an action in the other dimension defined as a number of time slots of an access channel, and choosing actions in turn according to the dimensions; then performing spectrum access according to the actions chosen; and finally, updating the Q-table in combination with biased information, wherein the biased information is a reward value. The system is configured to implement the proposed method. By adoption of the method, better performance is achieved, and the efficiency of spectrum access can be improved.
