End-to-End AI-Native Physical Layer for Robust 6G MIMO-OFDM: Adaptive Constellation Shaping and Attention-Based Detection
Sixth-generation (6G) physical-layer designs require robustness against non-analytical channel distortions and hardware impairments that violate classical linear assumptions. This paper presents an AI-native framework for MIMO-OFDM systems that jointly optimizes adaptive constellation shaping and neural detection throu...
