OTFS技术:研究现状与发展趋势
OTFS Technology:Research Status and Development Trends
摘要
Abstract
Orthogonal time frequency space(OTFS)modulation technology is a new signal modulation method proposed in recent years,which aims to deal with the problem of communication quality degradation caused by great frequency shifts in the typical high-mobility multipath transmission scenarios of next-generation wireless communication networks.OTFS technology maps the symbols to the delay-Doppler(DD)domain,and transforms them to the time-frequency domain through two-dimensional transformation to cope with the inter-carrier interference and inter-symbol interference caused by the majority of the great frequency shift and delay.The authors analyze and summarize the basic principles of OTFS technology,channel estimation,symbol detection and its combination with multiple access technology,and look forward to the future development trend of OTFS technology.关键词
