Abstract
A pilot information symbol sending method, a channel estimation method, and a communications device. The method includes: determining, based on a discrete Fourier transform DFT matrix and a sensing matrix, a pilot information symbol corresponding to each antenna on each pilot resource; and sending a corresponding pilot information symbol on each of the pilot resources for each of the antennas; where the sensing matrix is determined through training of channel information.
