DRL-Based Secure Adaptive Waveform for Satellite Communications

Conventional modulation techniques using fixed constellations, such as QAM and PSK, are increasingly challenged in dynamic and non-stationary satellite channels due to their limited adaptability and vulnerability to interception and signal classification. This paper proposes a deep reinforcement learning (DRL)-based ad...

On the Distribution of Pass Duration and Handover Rate in Mega Satellite Constellations

Low Earth orbit mega constellations are envisioned to revolutionize the current communication systems by providing auxiliary coverage that supplements beyond fifth generation communications. Nevertheless, these constellations exhibit extremely short pass durations owing to their low altitudes and inherent high orbital...

Pseudo-Noise Superposition for Finite-Alphabet Physical Layer Security

The results show that, at sufficiently high signal-tonoise ratio (SNR), the information rate becomes largely insensitive to PN power allocation, enabling near-perfect secrecy with M - QAM modulation-highlighting a key departure from Shannoncapacity-based secrecy analyses and underscoring the practicality of finite-alph...
