DOI: 10.1109/tbc.2024.3477000

Abstract: This paper proposes a broadcasting system with cooperative non-orthogonal multiple access (CO-NOMA) and successive refinement (SR) coding. Specifically, signals containing the basic description of the source and the refinement are overlapped at the transmitter, and… read more here.

DOI: 10.1109/tccn.2025.3526839

Abstract: Semantic Communication (SC) is an emerging technology aiming to surpass the Shannon limit. Traditional SC strategies often minimize signal distortion between the original and reconstructed data, neglecting perceptual quality, especially in low Signal-to-Noise Ratio (SNR)… read more here.

DOI: 10.1109/tit.2021.3107215

Abstract: We investigate the problem of the successive refinement for Wyner-Ziv coding with degraded side information and obtain a complete characterization of the rate region for the quadratic vector Gaussian case. The achievability part is based… read more here.

DOI: 10.1109/tit.2023.3244232

Abstract: We study the mismatched successive refinement problem where one uses Gaussian codebooks to compress an arbitrary memoryless source with successive minimum Euclidean distance encoding under the quadratic distortion measure. Specifically, we derive achievable refined asymptotics… read more here.

DOI: 10.3390/e27040370

Abstract: We consider the problem of successive-refinement coding for lossy compression of individual sequences, namely, compression in two stages, where in the first stage, a coarse description at a relatively low rate is sent from the… read more here.
