The development of communication systems critically depends on realistic channel models, yet there are no widely accepted standards in the underwater acoustic communications community. The situation is in stark contrast to terrestrial radio communications, where channel models have been standardized and are widely avai...

This work presents a joint signal processing and coding (JSPC) framework that iteratively refines channel estimates using decoded codewords, enabling reliable communication with minimal parity overhead and outperforming differentially coherent detection, particularly at low signal-to-noise ratio (SNR).

P2Flow is introduced, a phoneme-aware progressive flow matching (FM) framework designed for extreme SSR with three main strategies, which leverages phonetic information to reconstruct missing spectral components and employs a progressive architectural design that hierarchically restores distinct frequency regions.
