In response to the conflicting demands between real-time satellite communication and high-resolution synthetic aperture radar (SAR) imaging, we propose a method that aligns the data transmission rate with the imaging data volume. This approach balanc

In this paper, we explore the spectrum inference to achieve the spectrum occupancy in advance through analyzing the historical spectrum. We have conceived an offline-online cooperative framework. Specifically, the hyperparameters can be achieved on a

Cognitive radio (CR) is an efficient way to increase spectrum efficiency for the small low earth orbit (LEO) satellite communication system. Due to the implementation difficulties, we focus on the CR in the uplink transmission. In CR, the cognitive m

In this letter, a dynamic channel reservation (DCR) strategy based on deep Q network (DQN) is proposed for multi-service low earth orbit (LEO) satellite communication system. We develop a novel modeling method to represent DCR problem of multiple ser

In this letter, we use squared iterative method with parameter checking to accelerate the convergence rate of expectation/conditional maximization (ECM) algorithm when estimating the channel parameters blindly in flat fading non-Gaussian channels, an

By cognitive radio, the low Earth orbit (LEO) satellites may prefer to operate in the unlicensed spectrum which is open to all the users, and compete for the limited resources with terrestrial cognitive radio networks (CRNs). The competition can be r
