A method for cancelling transmitter interference of a multi-carrier radio frequency signal in a transceiver, characterized by comprising: coupling, by a multi-carrier interference receiver of the transceiver, a part of multi-carrier radio frequency signals output from a transmitter of the transceiver, processing the multi-carrier coupled signals, and outputting a digital signal for each carrier of the multi-carrier signal received by the multi-carrier interference receiver (601 a); and performing interference cancelling, by an interference cancelling unit of the receiver, on the respective digital signal of each carrier and a digital signal of each carrier output from a multi-carrier receiver of the transceiver, wherein the interference cancelling unit comprises adaptive equalization units (701A1,...701An), delay units (702B1,...701Bn) and subtraction units (703C1,...703Cn), and the number of the adaptive equalization units (701A1,...701An), the number of the delay units (702B1,...701Bn) and the number of the subtraction units (703C1,...703Cn) are corresponding to the number of the carriers of the multi-carrier radio frequency signal, wherein the performing the interference cancelling, by the interference cancelling unit of the receiver, on the respective digital signal of each carrier and the digital signal of each carrier output from a multi-carrier receiver of the transceiver comprises: performing, by the adaptive equalization units (701A1,...701An), adaptive equalization on the respective digital signal of each carrier output from the multi-carrier interference receiver (601 a); delaying, by the delay units (702B1,...701Bn), predetermined time of the digital signal of each carrier output from the multi-carrier receiver of the transceiver; and subtracting, by the subtraction units (703C1,...703Cn), the digital signal of each carrier after the adaptive equalization from the delayed digital signal of each carrier; wherein when the adaptive equalization is implemented in time domain, Finite Impulse Response, FIR, or Infinite Impulse Response, IIR, is used for filtration; when the adaptive equalization is implemented in frequency domain, Fast Fourier Transform, FFT, frequency domain amplitude and phase weighting, and Inverse Fast Fourier Transform, IFFT, in combination is used for filtration. coupling, by a multi-carrier interference receiver of the transceiver, a part of multi-carrier radio frequency signals output from a transmitter of the transceiver, processing the multi-carrier coupled signals, and outputting a digital signal for each carrier of the multi-carrier signal received by the multi-carrier interference receiver (601 a); and performing interference cancelling, by an interference cancelling unit of the receiver, on the respective digital signal of each carrier and a digital signal of each carrier output from a multi-carrier receiver of the transceiver, wherein the interference cancelling unit comprises adaptive equalization units (701A1,...701An), delay units (702B1,...701Bn) and subtraction units (703C1,...703Cn), and the number of the adaptive equalization units (701A1,...701An), the number of the delay units (702B1,...701Bn) and the number of the subtraction units (703C1,...703Cn) are corresponding to the number of the carriers of the multi-carrier radio frequency signal, wherein the performing the interference cancelling, by the interference cancelling unit of the receiver, on the respective digital signal of each carrier and the digital signal of each carrier output from a multi-carrier receiver of the transceiver comprises: performing, by the adaptive equalization units (701A1,...701An), adaptive equalization on the respective digital signal of each carrier output from the multi-carrier interference receiver (601 a); delaying, by the delay units (702B1,...701Bn), predetermined time of the digital signal of each carrier output from the multi-carrier receiver of the transceiver; and subtracting, by the subtraction units (703C1,...703Cn), the digital signal of each carrier after the adaptive equalization from the delayed digital signal of each carrier; wherein when the adaptive equalization is implemented in time domain, Finite Impulse Response, FIR, or Infinite Impulse Response, IIR, is used for filtration; when the adaptive equalization is implemented in frequency domain, Fast Fourier Transform, FFT, frequency domain amplitude and phase weighting, and Inverse Fast Fourier Transform, IFFT, in combination is used for filtration.
