Embedded Pilot-Aided Channel Estimation for OTFS in Delay–Doppler Channels
Embedded Pilot-Aided Channel Estimation for OTFS in Delay–Doppler Channels
Orthogonal time frequency space (OTFS) modulation was shown to provide significant error performance advantages over orthogonal frequency division multiplexing (OFDM) in delay-Doppler channels. In order to detect OTFS modulated data, the channel impulse response needs to be known at the receiver. In this paper, we propose embedded pilot-aided channel estimation …
