报告摘要：

Due to the limited bandwidth and long propagation delay in underwater acoustic networks (UANs), it is desirable to achieve multiple access without resource division and signaling exchanges. To this end, this paper proposes a novel coding-in-the-water multiple access (CWMA) for UANs, which takes asynchronous frame arrivals from multiple users as implicit coding structures rather than multiple user interference. A belief propagation (BP) algorithm is designed to decode the overlapped frames based on a factor graph, thereby achieving multi-user

detection without requiring strict synchronization. Simulation results demonstrate that CWMA outperforms the conventional successive interference cancellation, and a simple repeat-accumulate channel coding can significantly decrease the bit error rate of multiple access in UANs. The results reveal that CWMA is an efficient and promising solution to enable scalable UANs.
