Semantic-Aware Data-Aided Channel Estimation with Large Language Models for MIMO Systems
Sojeong Park, Jaehyun Choi, Hyun Jong Yang
Data-aided channel estimation enhances spectral efficiency by reusing detected symbols as virtual pilots. In this process, selecting only reliable symbols is crucial to prevent misdetected symbols from corrupting the channel estimate. However, conventional methods rely exclusivel…
