Toward Generalized LEO Channel Prediction: A Rapid Adaptation Time-Frequency Mamba Framework

Abstract

Accurate channel state information (CSI) prediction is pivotal for enhancing system capacity in low Earth orbit (LEO) satellite-terrestrial communications within the sixth-generation vision of global ubiquitous connectivity. However, the extreme mobility of LEO satellites, coupled with significant propagation delays, induces severe channel aging. Existing deep learning (DL) methods often struggle with non-stationary dynamics or generalize poorly across diverse global geographies. To address these challenges, we design the Evo-TFMamba, which is an evolutionary framework integrating time-frequency selective Mamba blocks with meta-learning for generalized CSI prediction. Experimental results demonstrate that the proposed Evo-TFMamba performs adaptive prediction according to the geographic coverage of LEO satellites. Meanwhile, it significantly enhances the model's generalization ability, particularly when faced with unseen channel environments in LEO satellite communication.
