1. A method for self-interference cancellation, comprising:
truncating a signal based on a detection window, wherein the signal comprises a receive signal and a self-interference signal which is associated with a transmit signal, and a length of the detection window is less than a symbol length;
performing self-interference channel estimation to obtain an estimation of a self-interference channel, based on the truncated signal and a first reference signal which is carried by the transmit signal and used for the self-interference channel estimation, wherein the first reference signal has a comb structure in a frequency domain; and
performing self-interference cancellation based on the transmit signal and the estimation of the self-interference channel.
