thông tin chi tiết - OTFS Channel Estimation and Detection for Overspread Channels
非常に大きな遅延広がりを持つチャネルにおけるOTFSチャネル推定と検出
大きな遅延広がりを持つチャネルにおいて、従来のチャネル推定手法では推定が失敗するため、2段階のチャネル推定手法を提案し、低複雑度のMRC検出アルゴリズムを修正することで、OTFSシステムの性能を改善する。
Efficient Channel Estimation and Detection for Orthogonal Time Frequency Space (OTFS) in Overspread Wireless Channels
This paper proposes a two-stage channel estimation scheme and a modified low-complexity maximum ratio combining (MRC) detection algorithm for OTFS systems operating in overspread wireless channels with very large delay spread.
