Abstract: A self-interference channel estimation method and device, where the method includes: determining, when a receive port of the first device receives a first signal, a second signal transmitted by a transmit port of the first device, wherein the first signal comprises a service signal from a second device, and comprises a self-interference signal originated from the second signal interfering, through an air interface, with the service signal from the second device, wherein service data comprised in the second signal is segmented into at least two segments, and a signal sequence formed by at least one preset character is inserted between the at least two segments of service data; estimating, according to the first signal and the second signal, the self-interference signal originated from the second signal; and eliminating the estimated self-interference signal from the received first signal.
