Study Finds OTFS Can Dramatically Cut Channel Training Costs in High-Mobility Networks

This story was originally published on HackerNoon at: https://hackernoon.com/study-finds-otfs-can-dramatically-cut-channel-training-costs-in-high-mobility-networks. OTFS significantly reduces channel training overhead in doubly-dispersive channels, outperforming OFDM as Doppler and delay effects increase.
