The invention discloses a method for generating a multi-carrier pilot sequence in a specified time interval based on FBMC modulation. The method comprises the following steps: generating a first multi-carrier pilot sequence on a specified frequency point in an OFDM modulation mode, and adding a window to the first multi-carrier pilot sequence to obtain a second multi-carrier pilot sequence; modulating a group of FBMC pilot symbols on a specified subcarrier and a specified time point so as to ensure the optimal similarity with the second multi-carrier pilot sequence on the whole; sending a data symbol behind the FBMC pilot symbols, and superposing correction amount on the FBMC pilot symbols, so that the correction amount can counteract the influence of the data symbol to the specified time interval; and adding the correction amount to the FBMC pilot symbols to obtain corrected FBMC pilot symbols, and performing modulation according to the corrected FBMC pilot symbols to obtain a fourth multi-carrier pilot sequence. According to the method provided by the invention, a group of ideal pilot symbols is found and is close to the first multi-carrier pilot sequence within the specified time interval as much as possible after passing through the fourth multi-carrier pilot sequence subjected to the FBMC modulation.
