A Spatio-temporal Residual Attention Network with SNR-adaptive Weighting for MIMO-OFDM Channel Estimation

This paper addresses channel estimation in MIMO-OFDM systems under time-varying Rician fading and spatially correlated propagation conditions, where reliable coherent detection requires accurate channel state information. Although least-squares (LS) estimation is simple and computationally efficient, it remains highly...
