Advancements in Machine Learning-Based Channel Estimation and Signal Detection for OTFS Systems
摘要
Abstract
OTFS modulation effectively combats ICI in high-mobility scenarios,offering significant performance gains over traditional OFDM and enhancing spectral efficiency and communication quality in high-Doppler environments,thus attracting extensive research interest in recent years.The primary focus and challenge in OTFS systems lie in channel estimation and signal detection.Artificial intelligence has emerged as a potent information processing tool,widely adopted across various industries.Machine learning,as a crucial branch of artificial intelligence,when integrated with the OTFS technique,addresses issues in channel estimation and signal detection,thereby improving system performance,stability,and reliability.This paper provides a comprehensive survey,analysis,comparison,and synthesis of current machine learning-based algorithms for channel estimation and signal detection in OTFS systems,identifies technical challenges,and discusses future technological development trends.关键词
