Blind Interactive Learning of Modulation Schemes: Multi-Agent Cooperation Without Co-Design
IEEE Access, 2020 We examine the problem of learning to cooperate in the context of wireless communication. In our setting, two agents must learn modulation schemes that enable them to communicate across a power-constrained additive white Gaussian noise channel.
