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...

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...
