A Foundation Model for Cross-Band CSI Reconstruction

Hongpu Zhang, Shu Sun, Ruifeng Gao, Tongjia Zhang, Feng Yang

Acquiring dense high-frequency channel state information (CSI) is costly in multi-band low-altitude wireless systems because pilot resources are limited and channel dimensions change with the carrier frequency, bandwidth, and antenna array size. We address cross-band CSI reconstr…Read more
