Diffusion Model Enhances MIMO Channel Estimation with LSTM Conditioning

Researchers have developed a novel diffusion model for MIMO channel estimation, leveraging a Long Short-Term Memory (LSTM) network to capture temporal dynamics. This model operates in the angular domain and incorporates a learnable SNR-gated shortcut to balance observation fidelity with generative priors across varying signal-to-noise ratios. To optimize inference speed, the framework utilizes a deterministic denoising diffusion implicit model (DDIM) approach with adaptive step allocation, demonstrating consistent performance gains over existing methods while maintaining low latency.
