Scalable Cross-Attention Transformer for Cooperative Multi-AP OFDM Uplink Reception
arXiv CS.LG

ArXi:2602.04728v2 Announce Type: replace-cross We propose a cross-attention Transformer for joint decoding of uplink OFDM signals received by multiple coordinated access points. A shared per-receiver encoder learns the time-frequency structure of each grid, and a token-wise cross-attention module fuses the receivers to produce soft log-likelihood ratios for a standard channel decoder without explicit channel estimates.
