Diffusion Model-Based Signal Recovery in Coexisting Satellite and Terrestrial Networks

Coexisting satellite and terrestrial networks present a unique set of challenges and opportunities when the two networks share the same spectrum. One of these challenges is the desired signal recovery in such interference-limited scenario. In this work, we design a signal recovery scheme in coexisting satellite and terrestrial networks. We formulate an optimization problem and propose a diffusion model to perform signal recovery. The proposed diffusion model leverages the denoising mechanism to recover the signals from noisy and distorted signals. The proposed diffusion model consists of encoder to encode the input to the latent space, U-Net for denoising, attention block to integrate different relevant feature to create better context for signal recovery, and decoder to deliver the recovered signal.
