Summary: Satellite image compression and denoising are crucial for earth observation. This letter proposes two neural network-based approaches, one for joint onboard compression and denoising, and the other for sequential onboard compression and on-ground denoising. The experiments show that both approaches outperform the current satellite imaging system, and their pros and cons are discussed.

Summary: In the past two decades, there has been a clear trend towards intelligent vehicles that provide safer, stress-free, and more enjoyable driving experiences. However, current intelligent vehicles have limited computing capabilities, making it challenging to meet the demands of delay-sensitive and computation-intensive applications. Vehicular task/computation offloading to edge cloud and vehicular cloudlet is considered a promising solution to improve network performance and application quality of service.

Summary: This letter investigates the power allocation problem in LEO satellite networks with rate-splitting multiple access (RSMA) mechanism based on deep reinforcement learning. A highly-effective proximal policy optimization (PPO) scheme is proposed to tackle the challenge of uncertain and limited channel distribution information. Simulation results demonstrate the superiority of the proposed scheme in terms of the sum rate metric with low computation complexity.

Summary: Advances in rocket technology have allowed companies like SpaceX and Amazon to enter the satellite internet business competitively. However, the limited resources of satellites make it challenging to provide sufficient internet service in densely populated areas. To address this issue, an adaptable aerial access network (AAN) composed of low-Earth orbit satellites and federated reinforcement learning (FRL)-enabled unmanned aerial vehicles (UAVs) has been proposed.

Summary: Current terrestrial communication networks mainly cover urban areas, while satellites have limitations in terms of latency and data rate. To overcome these issues, researchers have extensively studied the integration of terrestrial and satellite components for seamless broadband coverage. However, establishing an efficient hybrid satellite-terrestrial network still faces challenges due to the significant differences between satellite and terrestrial communications.
