Abstract
The present disclosure provides an FBMC-based pilot sending method, a channel estimation method, and a related apparatus. The FBMC-based pilot sending method includes: for each transmit antenna port, inserting a pilot symbol group at four consecutive FBMC time-frequency resource locations, where the pilot symbol group includes two auxiliary pilot symbols and two primary pilot symbols; calculating a transmit value of each auxiliary pilot symbol in the pilot symbol group according to obtained interference coefficient values and obtained transmit values of data symbols at time-frequency resource locations in a time-frequency resource location range in which each primary pilot symbol is interfered with; and sending the pilot symbol group, where the pilot symbol group includes the calculated transmit values of the auxiliary pilot symbols.
