Soft Graph Transformer for MIMO Detection

Jiadong Hong, Xinyu Bian, Zhaoyang Zhang

ICASSP 2026poster

We propose the Soft Graph Transformer (SGT), a soft-input-soft-output neural architecture designed for MIMO detection. While Maximum Likelihood (ML) detection achieves optimal accuracy, its exponential complexity makes it infeasible in large systems, and conventional message-passing algorithms rely…

Decentralizing Coherent Joint Transmission Precoding Via Deterministic Equivalents

Yuhao Liu, Xinyu Bian, Yizhou Xu, Tianqi Hou, Wenjie Wang, Yuyi Mao +1

ICASSP 2024accepted

In order to control the inter-cell interference for a multi-cell multi-user multiple-input multiple-output network, we consider the precoder design for coordinated multi-point with downlink coherent joint transmission. To avoid costly information exchange among the cooperating base stations in a cen…
