Non-Identical Diffusion Models in MIMO-OFDM Channel Generation 事件

Non-Identical Diffusion Models in MIMO-OFDM Channel Generation arXiv:2509.01641v3 Announce Type: replace-cross Abstract: We propose a novel diffusion model, termed the non-identical diffusion model, and investigate its application to wireless orthogonal frequency division multiplexing (OFDM) channel generation. Unlike the standard diffusion model that uses a scalar-valued time index to represent the global noise level, we extend this notion to an element-wise time indicator to capture local err
