Why is channel estimation in the DD domain rather than in the time-frequency domain? Thank you for your question. Because in the scene of high-speed vehicle movement, Doppler frequency shift and time delay will occur. DD domain can effectively reduce the impact of both on signal transmission, while the signal is greatly disturbed in time-frequency domain.
