Special Issue Information

Dear Colleagues,

As global communication demands surge, existing satellite communication systems face challenges including signal attenuation, resource limitations, and inadequate data processing capabilities. The incorporation of intelligent sensing technology has significantly improved the adaptability and operational efficiency of satellite systems, offering robust data support for signal processing, and thereby enhancing communication quality and reliability. Additionally, emerging wireless communication technologies such as efficient antenna designs and advanced signal processing strategies are now at the forefront of research interest. These technologies demonstrate immense potential for achieving global seamless coverage and enhancing service quality. This Special Issue aims to collect state-of-the-art research on enhancing satellite communication efficiency and intelligent sensing, including but not limited to intelligent sensing applications, efficient antenna technology, and advanced signal processing technology.

Advanced sensing technologies combined with efficient signal processing methods are employed for the collection and transmission of massive data, thereby promoting satellite communication technology, and improving global network efficiency and reliability. This Special Issue focuses on sensing technologies and signal processing strategies for satellite communications, urging the development of solutions that boost data transmission efficiency and expand coverage.

With the maturation of reusable launch vehicle technology and satellite mass-production capabilities, global mega-constellation projects have entered a phase of rapid expansion. Inter-satellite networking is a key approach for enhancing constellation performance, as it crucially impacts overall constellation effectiveness. However, existing studies mostly focus on the network layer protocol optimization, with insufficient attention to topological structure design, and fail to fully consider the engineering challenges associated with inter-orbit Inter-Satellite Links (ISLs). To address these issues, this paper proposes a heterogeneous ISL topology architecture for mega-constellations, centered on “stable high-speed laser backbone connection within intra-orbit planes + dynamic and flexible radio network between inter-orbit planes”. First, we clarify the optimization objectives for mega-constellation topological design under this architecture and theoretically prove that the optimization problem is NP-hard. Building on this, we introduce Topological Structure Units (TSUs) and employ a unit reuse strategy to simplify topological design. Furthermore, we propose a TSU-based heterogeneous ISL topological design algorithm. Considering the uneven satellite distribution across latitude zones within the constellation, we further propose a regional TSU-based topological design algorithm. Finally, through simulation experiments in Starlink and GW constellation scenarios, we conduct multi-dimensional verification to demonstrate the effectiveness of the proposed algorithms in reducing end-to-end delay and decreasing ISL hops.
