Special Issue Information

Dear Colleagues,

This Special Issue focuses on various innovations in modern communication technology, with a particular emphasis on Digital Signal Processing (DSP) and wireless communications. DSP plays a crucial role in modern communication systems, contributing significantly to signal processing and data analysis. Wireless communication technology has revolutionized our lives by enabling rapid data access and real-time information exchange. In this Special Issue, we will discuss a wide range of wireless communication technologies, including modulation/waveform, antenna techniques, coding, UAV and satellite communication, and AI wireless communication, and consider the future of wireless communication technology.

This Special Issue will provide insights into the latest trends and innovations in modern communication. We aim to contribute to the advancement of wireless communication by sharing the opinions and research findings of experts in various fields. We hope that this Special Issue will become a valuable resource for the development of wireless communication technology.

This paper proposes semantic interference cancellation (SemantIC)-Mamba, a novel framework that enhances semantic reconstruction accuracy while stably maintaining channel decoding performance. The proposed model follows a turbo structure in which information is complementarily exchanged between the semantic domain and the signal domain, progressively refining the reconstruction quality through iterative processing. To effectively perform this iterative information refinement, the proposed framework adopts a semantic autoencoder composed of three key components: a Conv block that extracts local features, a Mamba block that efficiently models long-range dependencies to integrate global contextual information, and an UpConv block that restores low-resolution features to the original resolution. Experimental results demonstrate that SemantIC-Mamba consistently achieves improved PSNR and classification accuracy compared to conventional SemantIC and SemantIC++ while maintaining channel decoding performance at a level comparable to existing models.
