Otfs precoding
WebThe merits of OTFS, including its conceptual connection with Radar, new coupling relationship between information and channels, robustness against interference, and linear scaling of spectral efficiency with respect to the number of antennas are revealed. The DD domain equalization and precoding are also briefly discussed. WebAdaptive Transmission With Frequency-Domain Precoding and Linear Equalization Over Fast Fading Channels Abstract: In this paper, the emerging orthogonal time frequency space (OTFS) modulation is firstly restructured as a precoded orthogonal frequency division multiplexing (OFDM) system, so that the well-established frequency-domain approach can …
