Deep reinforcement learning approach to MIMO precoding problem: Optimality and Robustness

no code implementations30 Jun 2020 Heunchul Lee, Maksym Girnyk, Jaeseong Jeong

To demonstrate the optimality of the proposed DRL-based precoding framework, we explicitly consider a simple MIMO environment for which the optimal solution can be obtained analytically and show that DQN- and DDPG-based agents can learn the near-optimal policy to map the environment state of MIMO system to a precoder that maximizes the reward function, respectively, in the codebook-based and non-codebook based MIMO precoding systems.
