Researchers have developed Diffusion-OAMP, a novel framework that combines diffusion models with the Orthogonal Approximate Message Passing (OAMP) algorithm for joint image compression and wireless transmission. This training-free approach leverages a pre-trained diffusion model as a nonlinear estimator, enhancing the OAMP algorithm's ability to incorporate generative priors. Experimental results indicate that Diffusion-OAMP outperforms traditional methods in scenarios involving various compression ratios and noise levels. AI
