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.

Abstract: A data receiving method and receiver are provided. A receiver determines the length of a pre-tail and the length of a post-tail of a frame by obtaining a start time and an end time of the main part of the signal of the frame at a fixed time, and determines a start time and an end time of a frame receiving window according to the start time and the end time of the main part of the signal of the frame and according to the length of the pre-tail and the length of the post-tail; and receiving a frame between the start time and the end time of the frame receiving window, so that the receiver can accurately and completely receive the main part of the signal and the pre-tail and post-tail of each frame to accurately and completely receive signals.
