Design and Performance Evaluation of a Link-Level Simulator for UWA

Key Points

• The research aims to design and implement a link-level simulator for underwater acoustic (UWA) communication reflecting real marine environments.
• Developed a modular link-level simulator integrating the Bellhop channel model and physical layer modules.
• Enabled performance comparisons of different algorithms through a GUI-based control system.
• Evaluated performance based on varying pilot resource lengths and codeword lengths under identical signaling conditions.
• Identified optimal equalizers varying by pilot resource length.
• Compared coding performance based on codeword length at the same signal-to-noise ratio.
