Abstract

Based on the background of underwater acoustic communication, this paper first examines the Orthogonal Time Frequency Space (OTFS) modulation technique, which exhibits strong time delay and Doppler tolerance. This modulation technique effectively mitigates time-selective fading caused by Doppler effects and offers superior performance advantages. Subsequently, the study delves into an analysis of current symbol detection algorithms in channel transmission, focusing on the limitations of the message passing (MP) algorithm. The paper proposes specific enhancements to the MP algorithm, based on its original framework, and assesses the system's performance using different modulation techniques, path numbers, and Doppler factors through simulation. The findings indicate that OTFS modulation outperforms OFDM modulation, and the improved MP algorithm surpasses Doppler modulation. Furthermore, the performance of the enhanced MP algorithm exceeds that of OFDM modulation, demonstrating its superiority over the traditional MP algorithm.
