| Zusammenfassung: | A pilot signal transmission method and apparatus, and a transmitting terminal. The method comprises: setting a first pilot signal, a second pilot signal, and a third pilot signal on a same subcarrier; and separately transmitting the first pilot signal, the second pilot signal, and the third pilot signal on three continuous symbols on the same subcarrier, wherein the first pilot signal, the second pilot signal, and the third pilot signal are all nonzero data, the phase difference between the first pilot signal and the second pilot signal is 90 degrees, the phase difference between the third pilot signal and the second pilot signal is 90 degrees, and the phase difference between the first pilot signal and the third pilot signal is 180 degrees. The technical solution saves resources for interference separation and pilot overheads, and improves channel estimation performance of a receiving terminal by means of interference cancellation, so as to improve channel estimation performance of a FBMC system or other sys |
