Relay mechanisms are an important part of communication systems and therefore naturally occurring molecular communication (MC) links. Multiple techniques have been proposed on how to design MC relay-aided setups, assuming synchronous operation and perfect timing during the decoding process. In this paper, we propose the use of a reinforcement learning (RL)-based synchronizer to continually adapt a decoding threshold and detect transmitted synchronization frames in a dynamic MC environment. We implement our approach for a macroscale MC testbed in a two-hop MC link with mobility and show its advantages compared to filter-based maximum likelihood (ML) synchronization. Our results exhibit the potential of an RL-based synchronizer with an equally high detection rate, a false positive rate two orders of magnitude lower, and a misalignment several bit times lower compared to the state of the art.
