Transmitter and Receiver Window Designs for Orthogonal Time Frequency Space Modulation
IEEE Transactions on Communications(2021)
摘要
In this paper, we investigate the impacts of transmitter and receiver windows on the performance of orthogonal time-frequency space (OTFS) modulation and propose window designs to improve the OTFS channel estimation and data detection performance. In particular, assuming ideal pulse shaping filters at the transceiver, we derive the impacts of windowing on the effective channel and its estimation p...
