description The invention discloses a self-adapting channel estimating method applied to 3GPP LTE system. The method comprises the following steps: (1) the LS (least square) channel estimating value at a pilot tone is computed according to reference signals in a receiving data field; (2) interpolation in the time domain is performed according to current frame pilot tone channel estimated value data and reserved delay frame pilot tone channel estimated value data, and a pilot matrix encrypted is obtained through computing; (3) channel delay spread is estimated according to LS estimation value at the pilot tone, then radio frequency channel filtering coefficient is selected according to the delay spread, and the frequency domain estimation value is computed; and (4) channel Doppler spread is estimated according to the LS estimation value at the pilot tone, then time domain filtering coefficient is selected according to the Doppler spread, and the time domain channel estimation value is computed. The self-adapting channel e
