Abstract(in English) | To balance the time delay caused by switching code rates and the system performance, we proposed a code rate switching algorithm in the dynamic communication environment based on reinforcement learning to increase the average transmission rate. We define a Markov Decision Process (MDP) and create a Q-table (as policy) that represents the expectation of the future reward for performing an action (R) under a particular state (SNR, R). Then, a proposed reinforcement learning algorithm is developed to find the optimal selection of coding rate. The simulation result shows that the proposed system significantly improved the transmission rate while satisfying the system performance requirement. |
