Generative AI-Based Probabilistic Constellation Shaping With Diffusion Models

no code implementations15 Nov 2023 Mehdi Letafati, Samad Ali, Matti Latva-aho

This way, we make the constellation symbols sent by the transmitter, and what is inferred (reconstructed) at the receiver become as similar as possible, resulting in as few mismatches as possible.

Secure Deep-JSCC Against Multiple Eavesdroppers

no code implementations5 Aug 2023 Seyyed AmirHossein Ameli Kalkhoran, Mehdi Letafati, Ecenaz Erdemir, Babak Hossein Khalaj, Hamid Behroozi, Deniz Gündüz

Adversarial accuracy of eavesdroppers are also studied over Rayleigh fading, Nakagami-m, and AWGN channels to verify the generalization of the proposed scheme.
