Design of Underwater Coaxial Cable Communication System Based on ARM Cortex-M3

This article designs and implements an underwater coaxial cable communication system based on ARM Cortex-M3. This article introduces for overall system design, system hardware design, coaxial cable transmission line model research, and system software design. After multiple tests, the communication system is stable and has a low packet loss rate, which has reference significance for data transmission of baseband coaxial cables.
