Spatial Modulation Based MIMO-OTFS Transmissions
2021 IEEE/CIC International Conference on Communications in China (ICCC Workshops)（2021）
摘要
Orthogonal time frequency space (OTFS) is a novel modulation scheme designed in delay-Doppler domain, which shows a strong Doppler-resilience over doubly-dispersive channels. The interaction between delay-Doppler channel and OTFS symbols allows a linear scaling of capacity with the multiple-input multiple-output (MIMO) order and simultaneously enables significant spectral efficiency improvements o...
